(4R,5R)-2-(2-(Diphenylphosphino)phenyl)-4,5-diphenyl-4,5-dihydrooxazole CAS 2680585-79-7 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 (4R,5R)-2-(2-(Diphenylphosphino)phenyl)-4,5-diphenyl-4,5-dihydrooxazole.

(4R,5R)-2-(2-(Diphenylphosphino)phenyl)-4,5-diphenyl-4,5-dihydrooxazole (CAS 2680585-79-7), molecular formula C33H26NOP and molecular weight 483.54 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of (4R,5R)-2-(2-(Diphenylphosphino)phenyl)-4,5-diphenyl-4,5-dihydrooxazole (C33H26NOP) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, organophosphorus functionality, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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), (4R,5R)-2-(2-(Diphenylphosphino)phenyl)-4,5-diphenyl-4,5-dihydrooxazole 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.
