Chemical Structure
Description
The molecular framework of 1-(5-Fluoro-2-hydroxyphenyl)-2-(triphenyl-lambda5-phosphanylidene)ethan-1-one (C26H20FO2P) is characterized by a steroid core, organophosphorus functionality, a hydroxyl group, an ether linkage, fluorine substitution. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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).
1-(5-Fluoro-2-hydroxyphenyl)-2-(triphenyl-lambda5-phosphanylidene)ethan-1-one (CAS 797054-15-0), molecular formula C26H20FO2P and molecular weight 414.41 g/mol, is a CATO reference standard with documented purity and traceability.
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.
