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 Ethyl 4,5-dimethyl-2-(4-nitrobenzamido)thiophene-3-carboxylate (CAS 313507-39-0), a certified reference material (molecular formula C16H16N2O5S, MW 348.37 g/mol) for analytical method development and quality control.
The molecular framework of Ethyl 4,5-dimethyl-2-(4-nitrobenzamido)thiophene-3-carboxylate (C16H16N2O5S) 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 Ethyl 4,5-dimethyl-2-(4-nitrobenzamido)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.
