Chemical Structure
Description
2-(2-(Diphenylphosphino)phenyl)-4,5-diphenyloxazole (CAS 2757082-54-3) is a high-purity analytical reference standard with the molecular formula C33H24NOP and a molecular weight of 481.52 g/mol.
Structurally, 2-(2-(Diphenylphosphino)phenyl)-4,5-diphenyloxazole (C33H24NOP) contains a nitrogen-containing heterocyclic scaffold, an amide group, organophosphorus functionality, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 22.5, corresponding to approximately 22 ring(s) or double-bond equivalent(s). With a molecular weight of 481.52 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), 2-(2-(Diphenylphosphino)phenyl)-4,5-diphenyloxazole 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.
