Chemical Structure

(3-methoxy-1,2-thiazol-5-yl)methanesulfonyl chloride CAS 1936670-65-3 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including (3-methoxy-1,2-thiazol-5-yl)methanesulfonyl chloride.

(3-methoxy-1,2-thiazol-5-yl)methanesulfonyl chloride (CAS 1936670-65-3), molecular formula C5H6ClNO3S2 and molecular weight 227.69 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of (3-methoxy-1,2-thiazol-5-yl)methanesulfonyl chloride (C5H6ClNO3S2) 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. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

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

CATO manufactures (3-methoxy-1,2-thiazol-5-yl)methanesulfonyl chloride under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
