Chemical Structure
Description
Based on its molecular formula C15H14F3O2P, Diphenyl(3,3,3-trifluoro-2-hydroxypropyl)phosphine oxide contains organophosphorus functionality, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution, a polycyclic aromatic system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 314.24 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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).
Diphenyl(3,3,3-trifluoro-2-hydroxypropyl)phosphine oxide (CAS 123271-28-3) is a high-purity analytical reference standard with the molecular formula C15H14F3O2P and a molecular weight of 314.24 g/mol.
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.
