5-Bromo-4-(methylthio)pyridine-3-sulfonamide CAS 1352507-63-1

Description

The occurrence of 5-Bromo-4-(methylthio)pyridine-3-sulfonamide is closely related to an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

5-Bromo-4-(methylthio)pyridine-3-sulfonamide (CAS 1352507-63-1), molecular formula C6H7BrN2O2S2 and molecular weight 283.17 g/mol, is a CATO reference standard with documented purity and traceability.

5-Bromo-4-(methylthio)pyridine-3-sulfonamide (C6H7BrN2O2S2) contains an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, bromine 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 5-Bromo-4-(methylthio)pyridine-3-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.
