4-Amino-N-(4-ethoxyphenyl)benzenesulfonamide hydrochloride CAS 1047620-35-8

Description

The occurrence of 4-Amino-N-(4-ethoxyphenyl)benzenesulfonamide hydrochloride 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.

4-Amino-N-(4-ethoxyphenyl)benzenesulfonamide hydrochloride (CAS 1047620-35-8), molecular formula C14H16N2O3SHCl and molecular weight 328.81 g/mol, is a CATO reference standard with documented purity and traceability.

4-Amino-N-(4-ethoxyphenyl)benzenesulfonamide hydrochloride (C14H16N2O3SHCl) 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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.
