(4R,5S)-4,5-Diphenyl-2-oxazolidinone CAS 86286-50-2

Description

The occurrence of (4R,5S)-4,5-Diphenyl-2-oxazolidinone is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

(4R,5S)-4,5-Diphenyl-2-oxazolidinone (CAS 86286-50-2), molecular formula C15H13NO2 and molecular weight 239.27 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, (4R,5S)-4,5-Diphenyl-2-oxazolidinone is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 239.27 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

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.

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.
