Description
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
CATO supplies 4-Bromo-2-(difluoromethyl)-3,6-difluoropyridine (CAS 1804453-33-5), a certified reference material (molecular formula C6H2BrF4N, MW 243.98 g/mol) for analytical method development and quality control.
4-Bromo-2-(difluoromethyl)-3,6-difluoropyridine (C6H2BrF4N) 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).
CATO manufactures 4-Bromo-2-(difluoromethyl)-3,6-difluoropyridine 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.
