Chemical Structure
Description
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.
2-(2-Chloroethyl)-4-methylthiazole (CAS 15357-20-7), molecular formula C6H8ClNS and molecular weight 161.65 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a nitrile group, sulfur-containing functionality, chlorine substitution, 2-(2-Chloroethyl)-4-methylthiazole is typically white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 161.65 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
