6-chloro-N-(5-methylisoxazol-3-yl)pyridine-3-sulfonamide CAS 622798-03-2

Description

The occurrence of 6-chloro-N-(5-methylisoxazol-3-yl)pyridine-3-sulfonamide is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

6-chloro-N-(5-methylisoxazol-3-yl)pyridine-3-sulfonamide (CAS 622798-03-2) is a high-purity analytical reference standard with the molecular formula C9H8ClN3O3S and a molecular weight of 273.70 g/mol.

6-chloro-N-(5-methylisoxazol-3-yl)pyridine-3-sulfonamide (C9H8ClN3O3S) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution. 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).

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
