Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
(2R)-2-[(4S)-4,5-Dihydro-4-(phenylmethyl)-2-oxazolyl]-1-(diphenylphosphino)piperidine (CAS 2757084-59-4) is a high-purity analytical reference standard with the molecular formula C27H29N2OP and a molecular weight of 428.51 g/mol.
The molecular framework of (2R)-2-[(4S)-4,5-Dihydro-4-(phenylmethyl)-2-oxazolyl]-1-(diphenylphosphino)piperidine (C27H29N2OP) is characterized by a steroid core, 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
As a certified reference material (CRM), (2R)-2-[(4S)-4,5-Dihydro-4-(phenylmethyl)-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.
