Chemical Structure
Description
Owing to a steroid core, organophosphorus functionality, a hydroxyl group, an ether linkage, 2-(Diphenylphosphino)-1-phenylethanone is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 304.32 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).
2-(Diphenylphosphino)-1-phenylethanone (CAS 82363-89-1) is a high-purity analytical reference standard with the molecular formula C20H17OP and a molecular weight of 304.32 g/mol.
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.
