Chemical Structure

1-(3,4-Dichlorobenzenesulfonyl)piperazine hydrochloride CAS 1169976-85-5 chemical structure

Description

The occurrence of 1-(3,4-Dichlorobenzenesulfonyl)piperazine 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.

CATO supplies 1-(3,4-Dichlorobenzenesulfonyl)piperazine hydrochloride (CAS 1169976-85-5), a certified reference material (molecular formula C10H12Cl2N2O2SHCl, MW 331.64 g/mol) for analytical method development and quality control.

Based on its molecular formula C10H12Cl2N2O2SHCl, 1-(3,4-Dichlorobenzenesulfonyl)piperazine hydrochloride contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 331.64 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.

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.
