Chemical Structure
Description
Structurally, Triphenylbis(2,2,2-trifluoroethoxy)phosphorane (C22H19F6O2P) contains a steroid core, organophosphorus functionality, a hydroxyl group, an ether linkage, fluorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 10.5, corresponding to approximately 10 ring(s) or double-bond equivalent(s). With a molecular weight of 460.35 g/mol, it falls into the moderately-high-molecular-weight range. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
Triphenylbis(2,2,2-trifluoroethoxy)phosphorane (CAS 67696-25-7), molecular formula C22H19F6O2P and molecular weight 460.35 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.
