Chemical Structure

N1,N1,N1,N5,N5,N5-Hexamethylpentane-1,5-diaminium bromide CAS 541-20-8 chemical structure

Description

N1,N1,N1,N5,N5,N5-Hexamethylpentane-1,5-diaminium bromide (CAS 541-20-8), molecular formula C11H28N2Br and molecular weight 268.26 g/mol, is a CATO reference standard with documented purity and traceability.

Based on its molecular formula C11H28N2Br, N1,N1,N1,N5,N5,N5-Hexamethylpentane-1,5-diaminium bromide contains bromine substitution; these features give the compound characteristic molecular-ion distribution patterns in mass spectrometry. The molecular weight of 268.26 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
