Chemical Structure
Description
CATO supplies Tetrakis(diethylamino)phosphonium bromide (CAS 81175-49-7), a certified reference material (molecular formula C16H40N4PBr, MW 399.40 g/mol) for analytical method development and quality control.
Tetrakis(diethylamino)phosphonium bromide (C16H40N4PBr) contains organophosphorus functionality, bromine substitution. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility; 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.
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.
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.
