Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including N-(Thiazol-2-yl)-2-(thiophen-2-ylsulfonyl)acetamide.
N-(Thiazol-2-yl)-2-(thiophen-2-ylsulfonyl)acetamide (CAS 1021020-73-4), molecular formula C9H8N2O3S3 and molecular weight 288.37 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C9H8N2O3S3, N-(Thiazol-2-yl)-2-(thiophen-2-ylsulfonyl)acetamide contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 288.37 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
