Chemical Structure
Description
The occurrence of 4-Methyl-1-(3-(triethylammonio)propyl)pyridin-1-ium bromide is closely related to a nitrile group, bromine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies 4-Methyl-1-(3-(triethylammonio)propyl)pyridin-1-ium bromide (CAS 79916-28-2), a certified reference material (molecular formula C15H28N2Br, MW 316.31 g/mol) for analytical method development and quality control.
Owing to a nitrile group, bromine substitution, 4-Methyl-1-(3-(triethylammonio)propyl)pyridin-1-ium bromide is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 316.31 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
