S-Phenyl diphenylphosphinothioate CAS 5510-78-1

Description

The occurrence of S-Phenyl diphenylphosphinothioate is closely related to a steroid core, sulfur-containing functionality, organophosphorus functionality, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

S-Phenyl diphenylphosphinothioate (CAS 5510-78-1) is a high-purity analytical reference standard with the molecular formula C18H15OPS and a molecular weight of 310.35 g/mol.

Owing to a steroid core, sulfur-containing functionality, organophosphorus functionality, a hydroxyl group, an ether linkage, S-Phenyl diphenylphosphinothioate is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 310.35 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.

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

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.
