Chemical Structure
Description
4-(Bromomethyl)-3,5-difluorobenzonitrile (CAS 1239964-16-9) is a high-purity analytical reference standard with the molecular formula C8H4BrF2N and a molecular weight of 232.02 g/mol.
4-(Bromomethyl)-3,5-difluorobenzonitrile (C8H4BrF2N) contains a nitrogen-containing heterocyclic scaffold, 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. 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-(Bromomethyl)-3,5-difluorobenzonitrile 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.
