Description

Compared with other compounds in its class, the molecular weight of 249.19 g/mol gives 6-Cyano-5-(difluoromethyl)-4-hydroxypyridine-2-sulfonamide distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies 6-Cyano-5-(difluoromethyl)-4-hydroxypyridine-2-sulfonamide (CAS 1806842-96-5), a certified reference material (molecular formula C7H5F2N3O3S, MW 249.19 g/mol) for analytical method development and quality control.

6-Cyano-5-(difluoromethyl)-4-hydroxypyridine-2-sulfonamide (C7H5F2N3O3S) 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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.

CATO manufactures 6-Cyano-5-(difluoromethyl)-4-hydroxypyridine-2-sulfonamide under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
