Description
As a certified reference material (CRM), 2-(Difluoromethyl)-3-fluoro-5-iodopyridine-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.
CATO supplies 2-(Difluoromethyl)-3-fluoro-5-iodopyridine-4-sulfonamide (CAS 1805046-56-3), a certified reference material (molecular formula C6H4F3IN2O2S, MW 352.07 g/mol) for analytical method development and quality control.
Owing to an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine/iodine substitution, an aromatic ring system, 2-(Difluoromethyl)-3-fluoro-5-iodopyridine-4-sulfonamide is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 352.07 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
