Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
N-(3-(2-Methoxyethyl)-6-(methylsulfonyl)benzo[d]thiazol-2(3H)-ylidene)-2-phenylacetamide (CAS 864977-43-5), molecular formula C19H20N2O4S2 and molecular weight 404.50 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of N-(3-(2-Methoxyethyl)-6-(methylsulfonyl)benzo[d]thiazol-2(3H)-ylidene)-2-phenylacetamide (C19H20N2O4S2) is characterized by a flavonoid core, an amide group, a sulfone group, 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. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
CATO manufactures N-(3-(2-Methoxyethyl)-6-(methylsulfonyl)benzo[d]thiazol-2(3H)-ylidene)-2-phenylacetamide 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.
