Tetrahexadecylammonium bromide CAS 139653-55-7

Description

The occurrence of Tetrahexadecylammonium bromide is closely related to bromine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

Tetrahexadecylammonium bromide (CAS 139653-55-7) is a high-purity analytical reference standard with the molecular formula C64H132NBr and a molecular weight of 995.67 g/mol.

Based on its molecular formula C64H132NBr, Tetrahexadecylammonium bromide contains bromine substitution; these features give the compound characteristic molecular-ion distribution patterns in mass spectrometry. The molecular weight of 995.67 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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.
