Chemical Structure
Description
Owing to a steroid core, a sulfone group, a phosphonate group, a hydroxyl group, an ether linkage, Diphenyl(2-phenyl-1-(propylsulfonyl)ethyl)phosphine oxide is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 412.48 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.
Diphenyl(2-phenyl-1-(propylsulfonyl)ethyl)phosphine oxide (CAS 101610-44-0), molecular formula C23H25O3PS and molecular weight 412.48 g/mol, is a CATO reference standard with documented purity and traceability.
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.
