Chemical Structure
Description
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.
(5-((4-Chlorophenyl)thio)-1-methyl-3-(trifluoromethyl)-1H-pyrazol-4-yl)methyl propionate (CAS 955962-82-0), molecular formula C15H14ClF3N2O2S and molecular weight 378.80 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of (5-((4-Chlorophenyl)thio)-1-methyl-3-(trifluoromethyl)-1H-pyrazol-4-yl)methyl propionate (C15H14ClF3N2O2S) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
CATO manufactures (5-((4-Chlorophenyl)thio)-1-methyl-3-(trifluoromethyl)-1H-pyrazol-4-yl)methyl propionate 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.
