5-Amino-2-chloro-N-(4-chlorophenyl)benzene-1-sulfonamide CAS 328028-10-0

Description

The molecular framework of 5-Amino-2-chloro-N-(4-chlorophenyl)benzene-1-sulfonamide (C12H10Cl2N2O2S) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

5-Amino-2-chloro-N-(4-chlorophenyl)benzene-1-sulfonamide (CAS 328028-10-0), molecular formula C12H10Cl2N2O2S and molecular weight 317.19 g/mol, is a CATO reference standard with documented purity and traceability.

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.
