4-Bromo-6-chloro-3-(difluoromethyl)pyridine-2-sulfonyl chloride CAS 1804658-16-9

Description

4-Bromo-6-chloro-3-(difluoromethyl)pyridine-2-sulfonyl chloride (C6H2BrCl2F2NO2S) contains an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine/chlorine/bromine substitution, an aromatic ring system. 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.

4-Bromo-6-chloro-3-(difluoromethyl)pyridine-2-sulfonyl chloride (CAS 1804658-16-9) is a high-purity analytical reference standard with the molecular formula C6H2BrCl2F2NO2S and a molecular weight of 340.96 g/mol.

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.

As a certified reference material (CRM), 4-Bromo-6-chloro-3-(difluoromethyl)pyridine-2-sulfonyl chloride meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
