2-Chloro-4-methylthiazole-5-carbonitrile CAS 82301-29-9

Description

Compared with other compounds in its class, the molecular weight of 158.61 g/mol gives 2-Chloro-4-methylthiazole-5-carbonitrile distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies 2-Chloro-4-methylthiazole-5-carbonitrile (CAS 82301-29-9), a certified reference material (molecular formula C5H3ClN2S, MW 158.61 g/mol) for analytical method development and quality control.

The molecular framework of 2-Chloro-4-methylthiazole-5-carbonitrile (C5H3ClN2S) is characterized by 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.

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.
