Chemical Structure

5-Amino-2-chloro-N-(2-chlorophenyl)benzene-1-sulfonamide CAS 327092-83-1 chemical structure

Description

Structurally, 5-Amino-2-chloro-N-(2-chlorophenyl)benzene-1-sulfonamide (C12H10Cl2N2O2S) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 8.0, corresponding to approximately 8 ring(s) or double-bond equivalent(s). With a molecular weight of 317.19 g/mol, it falls into the moderately-high-molecular-weight range. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

5-Amino-2-chloro-N-(2-chlorophenyl)benzene-1-sulfonamide (CAS 327092-83-1) is a high-purity analytical reference standard with the molecular formula C12H10Cl2N2O2S and a molecular weight of 317.19 g/mol.

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.
