Chemical Structure
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.
CATO supplies (2R)-2-[(4R)-4,5-Dihydro-4-(phenylmethyl)-2-oxazolyl]-1-(diphenylphosphino)piperidine (CAS 2757084-65-2), a certified reference material (molecular formula C27H29N2OP, MW 428.51 g/mol) for analytical method development and quality control.
Owing to a steroid core, an amide group, organophosphorus functionality, a hydroxyl group, an ether linkage, (2R)-2-[(4R)-4,5-Dihydro-4-(phenylmethyl)-2-oxazolyl]-1-(diphenylphosphino)piperidine is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 428.51 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
