1-[4-(3,4-Dichlorophenyl)-1,3-thiazol-2-yl]-5-(trifluoromethyl)-N-{[3-(trifluoromethyl)phenyl]methyl}-1H-pyrazole-4-carboxamide CAS 956738-14-0

Description

1-[4-(3,4-Dichlorophenyl)-1,3-thiazol-2-yl]-5-(trifluoromethyl)-N-{[3-(trifluoromethyl)phenyl]methyl}-1H-pyrazole-4-carboxamide (CAS 956738-14-0), molecular formula C22H12Cl2F6N4OS and molecular weight 565.32 g/mol, is a CATO reference standard with documented purity and traceability.

1-[4-(3,4-Dichlorophenyl)-1,3-thiazol-2-yl]-5-(trifluoromethyl)-N-{[3-(trifluoromethyl)phenyl]methyl}-1H-pyrazole-4-carboxamide (C22H12Cl2F6N4OS) contains a steroid core, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, fluorine/chlorine substitution. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
