Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 3-Oxo-1-phenyl-1,3-dihydroisobenzofuran-1-carboxamide.
CATO supplies 3-Oxo-1-phenyl-1,3-dihydroisobenzofuran-1-carboxamide (CAS 6319-77-3), a certified reference material (molecular formula C15H11NO3, MW 253.25 g/mol) for analytical method development and quality control.
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, 3-Oxo-1-phenyl-1,3-dihydroisobenzofuran-1-carboxamide is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 253.25 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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), 3-Oxo-1-phenyl-1,3-dihydroisobenzofuran-1-carboxamide 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.
