Alepee, Nathalie; Grandidier, Marie-Helene; Cotovio, Jose published an article on February 28 ,2019. The article was titled 《Usefulness of the EpiSkin reconstructed human epidermis model within Integrated Approaches on Testing and Assessment (IATA) for skin corrosion and irritation》, and you may find the article in Toxicology In Vitro.Synthetic Route of C6H3ClFNO2 The information in the text is summarized as follows:

Predictive capacity of the EpiSkin model was evaluated on 87 chems. using the Bottom-Up and the Top-Down testing approaches recommended within Integrated Approach on Testing and Assessment for the identification of both skin irritation and corrosion hazards. Classified (UN GHS Cat. 1 and Cat. 2) chems. were identified with a very high sensitivity (≥94%) and the non-classified (UN GHS Cat. 3 and No Cat.) chems. with an appropriate specificity (70%). Very high sensitivities were obtained for the identification of Cat. 1 chems. (≥98%), very high specificities for non-Cat. 1 chems. (93%), and accuracies of -95% for the identification of skin corrosives vs. non-corrosives by both approaches. Overall accuracies of 72% were found for predicting the single (sub)categories: non-classified, Cat. 2, Subcat. 1B/1C and Subcat. 1A. Results indicated the testing strategies to be more predictive than the individual assays on a conservative safety approach. Finally, no extreme misclassifications (no under-prediction of in vivo Subcat. 1A as non-Cat. 1, and no over-prediction of non-classified chem. as Subcat. 1A) occur. These findings, independently of the approach used, confirm the usefulness of the EpiSkin in vitro model for a safe prediction of the skin irritant and corrosive hazards of chems. In addition to this study using 3-Chloro-4-fluoronitrobenzene, there are many other studies that have used 3-Chloro-4-fluoronitrobenzene(cas: 350-30-1Synthetic Route of C6H3ClFNO2) was used in this study.

3-Chloro-4-fluoronitrobenzene(cas: 350-30-1) belongs to organochlorine compounds. The wide structural variety and divergent chemical properties of organochlorides lead to a broad range of names, applications, and properties. Aliphatic organochlorides are often alkylating agents as chlorine can act as a leaving group, which can result in cellular damage.Synthetic Route of C6H3ClFNO2

In 2019,Pest Management Science included an article by Liu, Jing-Bo; Li, Feng-Yun; Li, Yu-Xin; Zhang, Xiu-Lan; Hua, Xue-Wen; Xiong, Li-Xia; Li, Zheng-Ming. Reference of 3-Chloro-4-fluoronitrobenzene. The article was titled 《Synthesis, insecticidal evaluation and 3D-QSAR study of novel anthranilic diamide derivatives as potential ryanodine receptor modulators》. The information in the text is summarized as follows:

BACKGROUND : Anthranilic diamide insecticides control lepidopteran pests through selectively binding and activating insect ryanodine receptors. In order to search for potential insecticides targeting the ryanodine receptors, a series of anthranilic diamide analogs including trifluoromethyl, nitro, or chloro groups were designed and synthesized by the principle of bioisosterism and structural optimization. RESULTS : Insecticidal data indicated that some compounds displayed good activity against oriental armyworm (Mythimna separata) and diamondback moth (Plutella xylostella). In particular, the larvicidal activity of 6p against P. xylostella was 95% at 0.01 mg L-1, equivalent to chlorantraniliprole (85%, 0.01 mg L-1). The comparative mol. similarity index anal. model obtained indicated that hydrogen bond acceptor and electron-withdrawing groups in the R’3 group are favorable for insecticidal activity against M. separata, which is consistent with the structure-activity relationships. Moreover, the calcium imaging experiment indicated, like chlorantraniliprole, that 6h and 6p are interacting with the ryanodine receptor. CONCLUSION : Introducing trifluoromethyl, nitro, or chloro groups to a specific position in the N-phenylpyrazole could improve or maintain the activity against M. separata and P. xylostella. 6h and 6p could be used as potential lead compounds for ryanodine receptor modulators.Μ.

Name: 3-Chloro-4-fluoronitrobenzene. The article was titled 《The development of HEC-866 and its analogues for the treatment of idiopathic pulmonary fibrosis》. The information in the text is summarized as follows:

Idiopathic pulmonary fibrosis (IPF) is a chronic progressive lung disease with a typical survival time between three to five years. Two drugs, pirfenidone and nintedanib have been approved for the treatment of IPF, but they have limited efficacy. Thus, the development of new drugs to treat IPF is an urgent medical need. In this paper we report the discovery of a series of orally active pyrimidin-4(3H)-one analogs which exhibit potent activity in in vitro assays. Among them, HEC-866 showed promising efficacy in rat IPF models. Since HEC-866 also had good oral bioavailability, a long half-life and favorable long-term safety profiles, it was selected for further clin. evaluation.3-Chloro-4-fluoronitrobenzene(cas: 350-30-1Name: 3-Chloro-4-fluoronitrobenzene) was used in this study.

Khoramjouy, Mona; Rezaee, Elham; Khoshnevis, Afshan; Nazari, Maryam; Nematpour, Manijeh; Shahhosseini, Soraya; Tabatabai, Sayyed Abbas; Faizi, Mehrdad published their research in Bioorganic Chemistry in 2021. The article was titled 《Synthesis of 4,6-diphenylpyrimidin-2-ol derivatives as new benzodiazepine receptor ligands》.Electric Literature of C7H6BrCl The article contains the following contents:

In the quest for new benzodiazepine agonists with more selectivity and low adverse effects, novel derivatives of 4,6-diphenylpyrimidin-2-ol I (X = H, 2-F, 4-Cl, etc.; Y = 4-Me, 4-OMe, 4-NO2, etc.) were designed, synthesized, and evaluated. In this series, compound I (X = H; Y = 4-F) was the most potent analog in radioligand binding assay with an IC50 value of 19 nM compared to zolpidem (IC50 = 48 nM), a nonbenzodiazepine central BZD receptor (CBR) agonist. Some compounds with a variety of affinities in radioligand receptor binding assay were selected for in vivo evaluations. Compound I (X = H; Y = 4-Cl) (IC50 = 25 nM), which possessed chlorine instead of fluorine in position 4 of the Ph ring, exhibited an excellent ED50 value in most in vivo tests. Proper sedative-hypnotic effects, potent anticonvulsant activity, appropriate antianxiety effect, and no memory impairment served compound I (X = H; Y = 4-Cl), a desirable candidate as a benzodiazepine agonist. The pharmacol. effects of compound I (X = H; Y = 4-Cl) were antagonized by flumazenil, a selective BZD receptor antagonist, confirming the BZD receptors’ involvement in the biol. effects of the novel ligand. In the experiment, the researchers used many compounds, for example, 1-(Bromomethyl)-4-chlorobenzene(cas: 622-95-7Electric Literature of C7H6BrCl)

In 2022,Kim, Jong-Hyun; Kwon, Dong-Jun; DeVries, K. Lawrence; Park, Joung-Man published an article in Fibers and Polymers. The title of the article was 《Innovative Ru Catalyst Adopting for Improving Interfacial and Mechanical Properties on CF Fabric Reinforced ENB Composites》.COA of Formula: C43H72Cl2P2Ru The author mentioned the following in the article:

This study improved the interfacial and mech. properties of carbon fiber (CF) reinforced 5-ethylidene-2-norbornene (ENB) composites using the Ru catalyst coating method on CF for vacuum-assisted resin transfer molding (VARTM). Generally, the Ru catalyst added ENB was polymerized using mixing two materials. The interfacial and mech. properties of the composites containing Ru catalyst coated carbon fabric were higher than those in which Ru catalyst was mixed in the ENB before being embedded in the CF fabric. It can be mainly due to the uniform or random dispersion of Ru catalyst by two different manufacturing processes. The interfacial properties determined using the microdroplet test, e.g., the surface energy and work of adhesion, Wa, were consistent with macro-mech. properties. From the T-peel test combined with elec. resistance (ER), the Ru catalyst coated CF fabric/ENB composite responded reasonably well with high peeling strength. The different Ru catalyst processing methods resulted in different interfacial, mech., and elec. sensing properties, with the Ru catalyst coated CF composites typically having better properties. This study is about the Ru catalyst coated CF fabric, which can be applied to manufacture geometrically complex and large structural composites and will help improve product manufacturing efficiency and quality. The experimental part of the paper was very detailed, including the reaction process of Benzylidenebis(tricyclohexylphosphine)dichlororuthenium(cas: 172222-30-9COA of Formula: C43H72Cl2P2Ru)
