Chemical Structure
Description
8-Iodo-2H-chromen-2-one (CAS 1562426-96-3) is a high-purity analytical reference standard with the molecular formula C9H5IO2 and a molecular weight of 272.04 g/mol.
The molecular framework of 8-Iodo-2H-chromen-2-one (C9H5IO2) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage, iodine substitution, 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.
CATO manufactures 8-Iodo-2H-chromen-2-one 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.
