4,5-Diamino-3-(difluoromethyl)pyridine-2-sulfonyl chloride CAS 1805040-79-2

Description

As a certified reference material (CRM), 4,5-Diamino-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.

CATO supplies 4,5-Diamino-3-(difluoromethyl)pyridine-2-sulfonyl chloride (CAS 1805040-79-2), a certified reference material (molecular formula C6H6ClF2N3O2S, MW 257.65 g/mol) for analytical method development and quality control.

Based on its molecular formula C6H6ClF2N3O2S, 4,5-Diamino-3-(difluoromethyl)pyridine-2-sulfonyl chloride contains an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution, an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 257.65 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

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.
