5-(Methoxycarbonyl)-3,4-dimethylselenophene-2-carboxylic acid (CAS 90404-13-0), molecular formula C9H10O4Se and molecular weight 261.13 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 5-(Methoxycarbonyl)-3,4-dimethylselenophene-2-carboxylic acid (C9H10O4Se) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional 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.
