This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
CATO supplies (3-(2'-(2-Acetamidoethyl)-[2,4'-bithiazole]-4-carboxamido)propyl)dimethylsulfonium chloride (CAS 81645-12-7), a certified reference material (molecular formula C16H23N4O2S3Cl, MW 435.02 g/mol) for analytical method development and quality control.
(3-(2'-(2-Acetamidoethyl)-[2,4'-bithiazole]-4-carboxamido)propyl)dimethylsulfonium chloride (C16H23N4O2S3Cl) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
CATO manufactures (3-(2'-(2-Acetamidoethyl)-[2,4'-bithiazole]-4-carboxamido)propyl)dimethylsulfonium 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.
