6-Chloro-5-nitroimidazo[2,1-b][1,3]thiazole CAS 23576-89-8

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 6-Chloro-5-nitroimidazo[2,1-b][1,3]thiazole.

6-Chloro-5-nitroimidazo[2,1-b][1,3]thiazole (CAS 23576-89-8) is a high-purity analytical reference standard with the molecular formula C5H2ClN3O2S and a molecular weight of 203.61 g/mol.

6-Chloro-5-nitroimidazo[2,1-b][1,3]thiazole (C5H2ClN3O2S) contains an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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

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.
