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.
(Phenylthio)(triphenylphosphoranylidene)methyl acetate (CAS 442691-87-4), molecular formula C27H23O2PS and molecular weight 442.51 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a steroid core, a sulfone group, organophosphorus functionality, a hydroxyl group, an ether linkage, (Phenylthio)(triphenylphosphoranylidene)methyl acetate is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 442.51 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.
CATO manufactures (Phenylthio)(triphenylphosphoranylidene)methyl acetate under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
