Description
CATO manufactures 1-Ethyl-2-methylpyridinium 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.
1-Ethyl-2-methylpyridinium Bromide (CAS 32353-50-7) is a high-purity analytical reference standard with the molecular formula C8H12NBr and a molecular weight of 202.09 g/mol.
1-Ethyl-2-methylpyridinium Bromide (C8H12NBr) contains a nitrile group, bromine substitution. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
