Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
1-(3-Fluorophenyl)-2-(triphenylphosphoranylidene)ethanone (CAS 61748-01-4) is a high-purity analytical reference standard with the molecular formula C26H20FOP and a molecular weight of 398.41 g/mol.
Owing to a steroid core, organophosphorus functionality, a hydroxyl group, an ether linkage, fluorine substitution, 1-(3-Fluorophenyl)-2-(triphenylphosphoranylidene)ethanone is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 398.41 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).
CATO manufactures 1-(3-Fluorophenyl)-2-(triphenylphosphoranylidene)ethanone 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.
