4-Amino-5-chlorobenzene-1,3-disulfonamide CAS 1083-36-9

Description

The occurrence of 4-Amino-5-chlorobenzene-1,3-disulfonamide is closely related to an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies 4-Amino-5-chlorobenzene-1,3-disulfonamide (CAS 1083-36-9), a certified reference material (molecular formula C6H8ClN3O4S2, MW 285.73 g/mol) for analytical method development and quality control.

4-Amino-5-chlorobenzene-1,3-disulfonamide (C6H8ClN3O4S2) contains an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine 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.

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.
