(2S)-2-[(4S)-4,5-Dihydro-4-(1-methylethyl)-2-oxazolyl]-1-(diphenylphosphino)piperidine CAS 2757084-44-7

Description

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.

(2S)-2-[(4S)-4,5-Dihydro-4-(1-methylethyl)-2-oxazolyl]-1-(diphenylphosphino)piperidine (CAS 2757084-44-7) is a high-purity analytical reference standard with the molecular formula C23H29N2OP and a molecular weight of 380.46 g/mol.

Owing to a steroid core, an amide group, organophosphorus functionality, a hydroxyl group, an ether linkage, (2S)-2-[(4S)-4,5-Dihydro-4-(1-methylethyl)-2-oxazolyl]-1-(diphenylphosphino)piperidine is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 380.46 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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.
