Chemical Structure

1-Icosylpyridin-1-ium bromide CAS 134782-13-1 chemical structure

Description

1-Icosylpyridin-1-ium bromide (CAS 134782-13-1), molecular formula C25H46NBr and molecular weight 440.55 g/mol, is a CATO reference standard with documented purity and traceability.

Based on its molecular formula C25H46NBr, 1-Icosylpyridin-1-ium bromide contains a nitrile group, bromine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 440.55 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.
