N-(2-acetylphenyl)-2,3-dichlorobenzenesulfonamide CAS 303152-43-4

Description

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.

N-(2-acetylphenyl)-2,3-dichlorobenzenesulfonamide (CAS 303152-43-4) is a high-purity analytical reference standard with the molecular formula C14H11Cl2NO3S and a molecular weight of 344.21 g/mol.

N-(2-acetylphenyl)-2,3-dichlorobenzenesulfonamide (C14H11Cl2NO3S) 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, its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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.
