Description
CATO supplies 1,3-Dihydroisobenzofuran-5-ol (CAS 68747-25-1), a certified reference material (molecular formula C8H8O2, MW 136.15 g/mol) for analytical method development and quality control.
1,3-Dihydroisobenzofuran-5-ol (C8H8O2) contains a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. The carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
As a certified reference material (CRM), 1,3-Dihydroisobenzofuran-5-ol 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.
