Chemical Structure
Description
4-Bromo-2-(difluoromethyl)-5-methylpyridine (CAS 1805314-83-3), molecular formula C7H6BrF2N and molecular weight 222.03 g/mol, is a CATO reference standard with documented purity and traceability.
4-Bromo-2-(difluoromethyl)-5-methylpyridine (C7H6BrF2N) contains a nitrile group, fluorine/bromine substitution, an aromatic ring system. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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 4-Bromo-2-(difluoromethyl)-5-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.
