Description
CATO manufactures 5-Methoxy-7-hydroxycoumarin 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.
5-Methoxy-7-hydroxycoumarin (CAS 3067-10-5) is a high-purity analytical reference standard with the molecular formula C10H8O4 and a molecular weight of 192.17 g/mol.
The molecular framework of 5-Methoxy-7-hydroxycoumarin (C10H8O4) 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 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
