Tris(2,2,2-trifluoroethyl) phosphite Tris(2,2,2-trifluoroethoxy)phosphine 370-69-4 CAS 370-69-4

Description

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

CATO supplies Tris(2,2,2-trifluoroethyl) phosphite Tris(2,2,2-trifluoroethoxy)phosphine 370-69-4 (CAS 370-69-4), a certified reference material (molecular formula C6H6F9O3P, MW 328.07 g/mol) for analytical method development and quality control.

Tris(2,2,2-trifluoroethyl) phosphite Tris(2,2,2-trifluoroethoxy)phosphine 370-69-4 (C6H6F9O3P) contains a phosphonate group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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.
