Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 462.64 g/mol gives Didodecyldimethylammonium Bromide distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies Didodecyldimethylammonium Bromide (CAS 3282-73-3), a certified reference material (molecular formula C26H56NBr, MW 462.64 g/mol) for analytical method development and quality control.
Owing to bromine substitution, Didodecyldimethylammonium Bromide is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 462.64 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
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.
