2-(Difluoromethyl)-4-iodo-6-methylpyridine-3-sulfonamide CAS 1806983-45-8

Description

The occurrence of 2-(Difluoromethyl)-4-iodo-6-methylpyridine-3-sulfonamide is closely related to an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine/iodine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

2-(Difluoromethyl)-4-iodo-6-methylpyridine-3-sulfonamide (CAS 1806983-45-8), molecular formula C7H7F2IN2O2S and molecular weight 348.11 g/mol, is a CATO reference standard with documented purity and traceability.

2-(Difluoromethyl)-4-iodo-6-methylpyridine-3-sulfonamide (C7H7F2IN2O2S) contains an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine/iodine 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).

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-(Difluoromethyl)-4-iodo-6-methylpyridine-3-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.
