Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
methyl 7-hydroxy-1-benzothiophene-2-carboxylate (CAS 761428-40-4), molecular formula C10H8O3S and molecular weight 208.23 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of methyl 7-hydroxy-1-benzothiophene-2-carboxylate (C10H8O3S) is characterized by a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), 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 7-hydroxy-1-benzothiophene-2-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.
