(2S)-2-[(4S,5R)-4,5-Dihydro-4,5-diphenyl-2-oxazolyl]-1-(diphenylphosphino)piperidine CAS 2757084-49-2 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 (2S)-2-[(4S,5R)-4,5-Dihydro-4,5-diphenyl-2-oxazolyl]-1-(diphenylphosphino)piperidine.

(2S)-2-[(4S,5R)-4,5-Dihydro-4,5-diphenyl-2-oxazolyl]-1-(diphenylphosphino)piperidine (CAS 2757084-49-2), molecular formula C32H31N2OP and molecular weight 490.58 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, (2S)-2-[(4S,5R)-4,5-Dihydro-4,5-diphenyl-2-oxazolyl]-1-(diphenylphosphino)piperidine (C32H31N2OP) 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 18.5, corresponding to approximately 18 ring(s) or double-bond equivalent(s). With a molecular weight of 490.58 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.

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

As a certified reference material (CRM), (2S)-2-[(4S,5R)-4,5-Dihydro-4,5-diphenyl-2-oxazolyl]-1-(diphenylphosphino)piperidine 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.
