Chemical Structure
Description
CATO supplies Ethyl 6-iodo-4-oxo-4H-1-benzopyran-2-carboxylate (CAS 35204-44-5), a certified reference material (molecular formula C12H9IO4, MW 344.10 g/mol) for analytical method development and quality control.
Ethyl 6-iodo-4-oxo-4H-1-benzopyran-2-carboxylate (C12H9IO4) contains a carboxylic acid group, a hydroxyl group, an ether linkage, iodine substitution, an aromatic ring system. It is notably hygroscopic, halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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 Ethyl 6-iodo-4-oxo-4H-1-benzopyran-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.
