5-Chloro-1-methyl-3-phenyl-N-(4-(trifluoromethyl)phenyl)-1H-pyrazole-4-carboxamide CAS 318237-82-0 chemical structure

Description

The occurrence of 5-Chloro-1-methyl-3-phenyl-N-(4-(trifluoromethyl)phenyl)-1H-pyrazole-4-carboxamide is closely related to a steroid core, an amide group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies 5-Chloro-1-methyl-3-phenyl-N-(4-(trifluoromethyl)phenyl)-1H-pyrazole-4-carboxamide (CAS 318237-82-0), a certified reference material (molecular formula C18H13ClF3N3O, MW 379.76 g/mol) for analytical method development and quality control.

Structurally, 5-Chloro-1-methyl-3-phenyl-N-(4-(trifluoromethyl)phenyl)-1H-pyrazole-4-carboxamide (C18H13ClF3N3O) contains a steroid core, an amide group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 12.0, corresponding to approximately 12 ring(s) or double-bond equivalent(s). With a molecular weight of 379.76 g/mol, it falls into the moderately-high-molecular-weight range. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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.

CATO manufactures 5-Chloro-1-methyl-3-phenyl-N-(4-(trifluoromethyl)phenyl)-1H-pyrazole-4-carboxamide under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
