2,5-Dibromo-3-(difluoromethyl)pyridine-4-sulfonamide CAS 1805331-42-3

Description

Compared with other compounds in its class, the molecular weight of 365.98 g/mol gives 2,5-Dibromo-3-(difluoromethyl)pyridine-4-sulfonamide distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies 2,5-Dibromo-3-(difluoromethyl)pyridine-4-sulfonamide (CAS 1805331-42-3), a certified reference material (molecular formula C6H4Br2F2N2O2S, MW 365.98 g/mol) for analytical method development and quality control.

2,5-Dibromo-3-(difluoromethyl)pyridine-4-sulfonamide (C6H4Br2F2N2O2S) contains an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine/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.

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), 2,5-Dibromo-3-(difluoromethyl)pyridine-4-sulfonamide 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.
