Description

Compared with other compounds in its class, the molecular weight of 212.70 g/mol gives 5-(Chloromethyl)-1-methyl-3-(thiophen-2-yl)-1H-pyrazole distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies 5-(Chloromethyl)-1-methyl-3-(thiophen-2-yl)-1H-pyrazole (CAS 876316-96-0), a certified reference material (molecular formula C9H9ClN2S, MW 212.70 g/mol) for analytical method development and quality control.

The molecular framework of 5-(Chloromethyl)-1-methyl-3-(thiophen-2-yl)-1H-pyrazole (C9H9ClN2S) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality, 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.

As a certified reference material (CRM), 5-(Chloromethyl)-1-methyl-3-(thiophen-2-yl)-1H-pyrazole meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
