Chemical Structure
Description
1-(2-Carboxyethyl)-4-methylpyridin-1-ium bromide (CAS 49563-66-8), molecular formula C9H12NO2Br and molecular weight 246.10 g/mol, is a CATO reference standard with documented purity and traceability.
1-(2-Carboxyethyl)-4-methylpyridin-1-ium bromide (C9H12NO2Br) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, bromine substitution. Halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO manufactures 1-(2-Carboxyethyl)-4-methylpyridin-1-ium bromide under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
