Chemical Structure
Description
CATO supplies 4-Ethyl-7-hydroxyisobenzofuran-1(3H)-one (CAS 62596-60-5), a certified reference material (molecular formula C10H10O3, MW 178.18 g/mol) for analytical method development and quality control.
4-Ethyl-7-hydroxyisobenzofuran-1(3H)-one (C10H10O3) contains a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. It is notably hygroscopic, 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.
As a certified reference material (CRM), 4-Ethyl-7-hydroxyisobenzofuran-1(3H)-one meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
