Description

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.

4-Amino-2-(difluoromethyl)-6-hydroxypyridine-3-sulfonamide (CAS 1805138-83-3) is a high-purity analytical reference standard with the molecular formula C6H7F2N3O3S and a molecular weight of 239.20 g/mol.

4-Amino-2-(difluoromethyl)-6-hydroxypyridine-3-sulfonamide (C6H7F2N3O3S) contains an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

As a certified reference material (CRM), 4-Amino-2-(difluoromethyl)-6-hydroxypyridine-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.
