Chemical Structure

2-Ethyl-4-methyl-2,5-dihydrothiazole CAS 41803-21-8 chemical structure

Description

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

CATO supplies 2-Ethyl-4-methyl-2,5-dihydrothiazole (CAS 41803-21-8), a certified reference material (molecular formula C6H11NS, MW 129.22 g/mol) for analytical method development and quality control.

Owing to a nitrile group, sulfur-containing functionality, 2-Ethyl-4-methyl-2,5-dihydrothiazole is typically white to off-white liquid. Its solid-state physicochemical attributes — including a molecular weight of 129.22 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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.
