Description
CATO manufactures 2-Bromo-3-fluoropyridine 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.
2-Bromo-3-fluoropyridine (CAS 40273-45-8) is a high-purity analytical reference standard with the molecular formula C5H3BrFN and a molecular weight of 175.99 g/mol.
2-Bromo-3-fluoropyridine (C5H3BrFN) contains a nitrile group, fluorine/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.
