Chemical Structure

1,3-Thiazole-2-carboxamide CAS 16733-85-0 chemical structure

Description

1,3-Thiazole-2-carboxamide (CAS 16733-85-0) is a high-purity analytical reference standard with the molecular formula C4H4N2OS and a molecular weight of 128.15 g/mol.

The molecular framework of 1,3-Thiazole-2-carboxamide (C4H4N2OS) is characterized by an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage. 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. 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.
