SDS of cas: 10007-84-8On May 31, 2015, Solyanikova, Inna P.; Emelyanova, Elena V.; Shumkova, Ekaterina S.; Egorova, Darya O.; Korsakova, Ekaterina S.; Plotnikova, Elena G.; Golovleva, Ludmila A. published an article in International Biodeterioration & Biodegradation. The article was 《Peculiarities of degradation of benzoate and its chloro- and hydroxy-substituted analogs by actinobacteria》. The article mentions the following:

This work investigates the ability of representatives of four actinobacterial genera (Arthrobacter, Microbacterium, Rhodococcus, Gordonia) to degrade benzoic acid and its hydroxylated or chlorinated analogs. Benzoate, 3-chlorobenzoate and 4-hydroxybenzoate were shown to support growth of most strains. We determined the maximal specific growth rates and doubling times for bacteria grown on these substrates. We examined the substrate specificities of actinobacterial benzoate dioxygenases towards 16 aromatic chems. The specificities varied among species, they were narrow for Rhodococcus opacus 1CP and Gordonia polyisoprenivorans 135 and broad for Rhodococcus ruber P25 and Microbacterium sp. B51. The genes encoding the benzoate dioxygenase α-subunit from R. opacus 1CP, R. opacus 6a, R. ruber P25, Rhodococcus wratislaviensis P1 and R. wratislaviensis G10 which were isolated at distant sites exhibited between 88 and 97% homol. with the homologous gene of Rhodococcus jostii RHA1. This indicates a common origin of these genes. Notably, in some strains, catechol 1,2-dioxygenase and gentisate dioxygenase were induced simultaneously during growth on benzoate. In the part of experimental materials, we found many familiar compounds, such as Sodium 2,6-dichlorobenzoate(cas: 10007-84-8SDS of cas: 10007-84-8)

Sodium 2,6-dichlorobenzoate(cas: 10007-84-8) belongs to organochlorine compounds. Alkanes and aryl alkanes may be chlorinated under free radical conditions, with UV light. The haloform reaction, using chlorine and sodium hydroxide, is also able to generate alkyl halides from methyl ketones, and related compounds. Chloroform was formerly produced thus.SDS of cas: 10007-84-8

Similar tests were run to determine the dilution needed to inhibit growth of M. smegmatus for 6 days and data are given. The most active compounds are those in which the hydrophilic group occupies the para position to the O bridge and its basic or acidic character is not significant. A grouping which possesses high water solubility depresses biol. activity, as when 2 HO, 2 H2N, or 2 guanyl groups are present. Introduction of 1 or 2 Cl substituents increases the antitubercular activity; further halogenation has little addnl. effect. The greatest activity is shown by compounds in which the halogens are shared by both Bz nuclei. Compounds which most strongly depress O uptake of yeast cells have the highest antitubercular activity. All of the Ph2O derivatives tested required a dilution of 50,000 or less in the presence of serum (in vivo) as compared to an active dilution of 1:500,000 for streptomycin.2-Amino-2,4-dichlorodiphenyl ether(cas: 56966-48-4Safety of 2-Amino-2,4-dichlorodiphenyl ether) was used in this study.

2-Amino-2,4-dichlorodiphenyl ether(cas: 56966-48-4) belongs to anime. Many important products require amines as part of their syntheses. Methylamine is utilized in the production of the analgesic meperidine (trade name Demerol) and the photographic developer Metol (trademark), and dimethylamine is used in the synthesis of the antihistamine diphenhydramine (trade name Benadryl), the solvent dimethylformamide (DMF), and the rocket propellant 1,1-dimethylhydrazine.

A novel series of benzopyran-3-carboxamide derivatives I (R = Ph, 2-chlorophenyl, 4-methoxyphenyl, 2-chloro-3-fluorophenyl, etc.) have been designed and synthesized using a smooth and linear multistep synthesis. Amidation of coumarin-3-carboxylic acid with glycine Et ester in the presence of EDC.HCl and HOBt as coupling agent followed by the hydrolysis results in the formation of key synthon, [(2-oxo-2H-1-benzopyran-3-carbonyl) amino] acetic acid which is further coupled with substituted aryl amines RCH2NH2 using HATU in combination with Hunig’s base to get the target compounds I. The synthesized compounds I have been screened for their in vitro antibacterial and antioxidant activity and the results are expressed as MIC and IC 50 values resp. Further, the binding ability of synthesized compounds I with different proteins have been examined by mol. docking studies. In the experiment, the researchers used many compounds, for example, (2-Chloro-3-fluorophenyl)methanamine(cas: 72235-54-2COA of Formula: C7H7ClFN)

HPLC of Formula: 150444-93-2On May 21, 1995 ,《Directed lithiation of unprotected benzoic acids》 appeared in Journal of the Chemical Society, Perkin Transactions 1: Organic and Bio-Organic Chemistry. The author of the article were Bennetau, Bernard; Mortier, Jacques; Moyroud, Joeel; Guesnet, Jean-Luc. The article conveys some information:

Benzoic acid gives the ortho-lithiated species (2-carboxyphenyl)lithium (lithium salt) under standard conditions. Reaction of (2-carboxyphenyl)lithium (lithium salt) at -78 °C with either Me iodide, di-Me disulfide, hexachloroethane, or 1,2-dibromotetrachloroethane gives the ortho-substituted product. Intramol. competition between the carboxylic acid and methoxy, chloro, fluoro, or diethylamino functions in ortho- and para-substituted benzoic acids establishes the carboxylic acid group to be of intermediate capacity in directing metalation. Complimentarity of directing effects is observed with the chloro and fluoro groups in the meta-substituted benzoic acids but not with the methoxy and trifluoromethyl groups. Electrophile introduction into meta- and para-lithiated benzoates occurs with equal efficacy and comparable scope. The 2,4-dihalobenzoic acids undergo hydrogen/metal exchange at the position flanked by both halogen substituents. 2,2-Difluoro-1,3-benzodioxole-4-carboxylic acid undergoes lithiation adjacent to the oxygen atom. By use of such methods, routes to benzoic acids contiguously tri- and tetra-substituted with a variety of functionalities have been developed. The experimental part of the paper was very detailed, including the reaction process of 2-Chloro-3,4-difluorobenzoic acid(cas: 150444-93-2HPLC of Formula: 150444-93-2)
