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-(Trifluoromethyl)phenoxy)-3-(triphenyl-l5-phosphanylidene)propan-2-one (CAS 73718-90-8) is a high-purity analytical reference standard with the molecular formula C27H22F3O2P and a molecular weight of 466.43 g/mol.
Owing to a steroid core, organophosphorus functionality, a hydroxyl group, an ether linkage, fluorine substitution, 1-(3-(Trifluoromethyl)phenoxy)-3-(triphenyl-l5-phosphanylidene)propan-2-one is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 466.43 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
