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 Methyl 2-((5,6-dimethyl-2H-pyran-2-yl)(ethoxy)amino)-4-methyl-5-(m-tolylcarbamoyl)thiophene-3-carboxylate (CAS 335409-78-4), a certified reference material (molecular formula C24H28N2O5S, MW 456.55 g/mol) for analytical method development and quality control.
The molecular framework of Methyl 2-((5,6-dimethyl-2H-pyran-2-yl)(ethoxy)amino)-4-methyl-5-(m-tolylcarbamoyl)thiophene-3-carboxylate (C24H28N2O5S) 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 Methyl 2-((5,6-dimethyl-2H-pyran-2-yl)(ethoxy)amino)-4-methyl-5-(m-tolylcarbamoyl)thiophene-3-carboxylate 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.
