Description
CATO manufactures 2-Bromo-5-iodo-3-methylpyridine 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.
CATO supplies 2-Bromo-5-iodo-3-methylpyridine (CAS 65550-78-9), a certified reference material (molecular formula C6H5BrIN, MW 297.92 g/mol) for analytical method development and quality control.
Based on its molecular formula C6H5BrIN, 2-Bromo-5-iodo-3-methylpyridine contains a nitrile group, bromine/iodine substitution, an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 297.92 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
