Chemical Structure

3-Methyl-1,4,2-dithiazol-5-one CAS 85559-04-2 chemical structure

Description

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

CATO supplies 3-Methyl-1,4,2-dithiazol-5-one (CAS 85559-04-2), a certified reference material (molecular formula C3H3NOS2, MW 133.19 g/mol) for analytical method development and quality control.

The molecular framework of 3-Methyl-1,4,2-dithiazol-5-one (C3H3NOS2) 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.

CATO manufactures 3-Methyl-1,4,2-dithiazol-5-one 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.
