Chemical Structure

6-Chloro-5-(difluoromethyl)-4-fluoropyridine-2-sulfonamide CAS 1806930-01-7 chemical structure

Description

The occurrence of 6-Chloro-5-(difluoromethyl)-4-fluoropyridine-2-sulfonamide is closely related to an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

6-Chloro-5-(difluoromethyl)-4-fluoropyridine-2-sulfonamide (CAS 1806930-01-7) is a high-purity analytical reference standard with the molecular formula C6H4ClF3N2O2S and a molecular weight of 260.62 g/mol.

6-Chloro-5-(difluoromethyl)-4-fluoropyridine-2-sulfonamide (C6H4ClF3N2O2S) contains an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine/chlorine 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. 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.

As a certified reference material (CRM), 6-Chloro-5-(difluoromethyl)-4-fluoropyridine-2-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.
