Description
CATO manufactures 3,5-Dibromo-2,6-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.
CATO supplies 3,5-Dibromo-2,6-difluoropyridine (CAS 685517-84-4), a certified reference material (molecular formula C5HBr2F2N, MW 272.87 g/mol) for analytical method development and quality control.
3,5-Dibromo-2,6-difluoropyridine (C5HBr2F2N) 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
