Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
2-[2-(Diphenylphosphino)phenyl]-4,5-dihydro-4,4-dimethyloxazole (CAS 64691-33-4) is a high-purity analytical reference standard with the molecular formula C23H22NOP and a molecular weight of 359.40 g/mol.
The molecular framework of 2-[2-(Diphenylphosphino)phenyl]-4,5-dihydro-4,4-dimethyloxazole (C23H22NOP) 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
