Description

The molecular framework of U0MP1K4TL8 69812-29-9 EINECS 274-127-7 2-Acetamido-4-methylthiazole-5-sulphonyl chloride 5-Thiazolesulfonyl chloride, 2-(acetylamino)-4-methyl- UNII-U0MP1K4TL8 2-Acetamido-4-methylthiazole-5-sulfonyl chloride (C6H11ClN2O3S2) is characterized by an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution. 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

U0MP1K4TL8 69812-29-9 EINECS 274-127-7 2-Acetamido-4-methylthiazole-5-sulphonyl chloride 5-Thiazolesulfonyl chloride, 2-(acetylamino)-4-methyl- UNII-U0MP1K4TL8 2-Acetamido-4-methylthiazole-5-sulfonyl chloride (CAS 69812-29-9) is a high-purity analytical reference standard with the molecular formula C6H11ClN2O3S2 and a molecular weight of 258.75 g/mol.

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.
