Methyl 3-(4-(phenylsulfonamido)phenoxy)thiophene-2-carboxylate (CAS 900015-17-0), molecular formula C18H15NO5S2 and molecular weight 389.45 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of Methyl 3-(4-(phenylsulfonamido)phenoxy)thiophene-2-carboxylate (C18H15NO5S2) 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
