Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 5-Benzoyltetrahydro-2,2,2,5-tetraphenyl-1,2-oxaphosphole.
5-Benzoyltetrahydro-2,2,2,5-tetraphenyl-1,2-oxaphosphole (CAS 22950-45-4), molecular formula C34H29O2P and molecular weight 500.57 g/mol, is a CATO reference standard with documented purity and traceability.
5-Benzoyltetrahydro-2,2,2,5-tetraphenyl-1,2-oxaphosphole (C34H29O2P) contains organophosphorus functionality, a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system. 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), 5-Benzoyltetrahydro-2,2,2,5-tetraphenyl-1,2-oxaphosphole 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.
