Chemical Structure

3-(Chloromethyl)-5-(trifluoromethyl)-1H-pyrazole CAS 1462379-36-7 chemical structure

Description

The occurrence of 3-(Chloromethyl)-5-(trifluoromethyl)-1H-pyrazole is closely related to a nitrile group, fluorine/chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

3-(Chloromethyl)-5-(trifluoromethyl)-1H-pyrazole (CAS 1462379-36-7), molecular formula C5H4ClF3N2 and molecular weight 184.55 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 3-(Chloromethyl)-5-(trifluoromethyl)-1H-pyrazole (C5H4ClF3N2) is characterized by a nitrile group, fluorine/chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, 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).

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 3-(Chloromethyl)-5-(trifluoromethyl)-1H-pyrazole 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.
