Description
CATO supplies Benzoic acid, 2-(diphenylphosphino)-, methyl ester (CAS 79932-99-3), a certified reference material (molecular formula C20H17O2P, MW 320.32 g/mol) for analytical method development and quality control.
Structurally, Benzoic acid, 2-(diphenylphosphino)-, methyl ester (C20H17O2P) contains a steroid core, organophosphorus functionality, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 12.5, corresponding to approximately 12 ring(s) or double-bond equivalent(s). With a molecular weight of 320.32 g/mol, it falls into the moderately-high-molecular-weight range. 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), Benzoic acid, 2-(diphenylphosphino)-, methyl ester 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.
