Chemical Structure

Butyltris(dibutylamino)phosphonium bromide CAS 73790-36-0 chemical structure

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.

Butyltris(dibutylamino)phosphonium bromide (CAS 73790-36-0), molecular formula C28H63N3PBr and molecular weight 552.71 g/mol, is a CATO reference standard with documented purity and traceability.

Butyltris(dibutylamino)phosphonium bromide (C28H63N3PBr) 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. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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.
