Chemical Structure

4-(chloromethyl)thiazole CAS 3364-76-9 chemical structure

Description

4-(chloromethyl)thiazole (CAS 3364-76-9) is a high-purity analytical reference standard with the molecular formula C4H8ClNS and a molecular weight of 137.63 g/mol.

Owing to sulfur-containing functionality, chlorine substitution, 4-(chloromethyl)thiazole is typically white to off-white liquid. Its solid-state physicochemical attributes — including a molecular weight of 137.63 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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.
