4-Bromo-3-chloro-2-(difluoromethyl)-5-nitropyridine CAS 1806910-03-1 chemical structure

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-3-chloro-2-(difluoromethyl)-5-nitropyridine (CAS 1806910-03-1), a certified reference material (molecular formula C6H2BrClF2N2O2, MW 287.45 g/mol) for analytical method development and quality control.

4-Bromo-3-chloro-2-(difluoromethyl)-5-nitropyridine (C6H2BrClF2N2O2) contains an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine/chlorine/bromine substitution, an aromatic ring system. It is notably hygroscopic, halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; 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.

CATO manufactures 4-Bromo-3-chloro-2-(difluoromethyl)-5-nitropyridine 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.
