Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO supplies 1-Bromo-4-chloro-2-(difluoromethyl)-3-fluorobenzene (CAS 1628524-81-1), a certified reference material (molecular formula C7H3BrClF3, MW 259.45 g/mol) for analytical method development and quality control.
1-Bromo-4-chloro-2-(difluoromethyl)-3-fluorobenzene (C7H3BrClF3) contains fluorine/chlorine/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).
CATO manufactures 1-Bromo-4-chloro-2-(difluoromethyl)-3-fluorobenzene 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.
