Chemistry is the experimental science by definition. We want to make observations to prove hypothesis. For this purpose, we perform experiments in the lab. , Computed Properties of C7H5ClF3N, 432-21-3, Name is 2-Amino-6-chlorobenzotrifluoride, molecular formula is C7H5ClF3N, belongs to chlorides-buliding-blocks compound.

One-pot ball-milling preparation of cetylpyridinium chloride/alpha-zirconium phosphate composite for simultaneous detection of ascorbic acid and dopamine
In this study, we report a rapid and facile synthesis of cetylpyridinium chloride (CPC) intercalated alpha-zirconium phosphate (alpha-ZrP) by a one-pot ball-milling method. The obtained intercalation composite were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM), fourier transform infrared spectroscopy (FT-IR) and thermogravimetric analysis (TGA). The effect of milling time on the intercalation behavior was investigated and CPC can be successfully inserted into the gallery of alpha-ZrP after 2 h of grinding. The as-prepared CPC/alpha-ZrP composite was used for the modification of glass carbon electrode (GCE) and simultaneous detection of ascorbic acid (AA) and dopamine (DA) via cyclic voltammetry (CV) and differential pulse voltammetry (DPV) techniques. AA and DA exhibited two well-resolved oxidation peaks on the CPC/alpha-ZrP modified electrode with a potential difference of 307 mV. The calibration curves obtained are linear for the currents versus AA and DA concentrations in the range 40-1500 mu M and 13-520 mu M, with the detection limits (S/N = 3) are 10 mu M and 3.3 mu M, respectively. The modified electrode could provide a new platform for the determination of AA and DA in terms of excellent reproducibility and stability. (C) 2020 Elsevier B.V. All rights reserved.
