Chemical Structure

4-Chlorobenzenesulfinamide CAS 16096-86-9 chemical structure

Description

The molecular framework of 4-Chlorobenzenesulfinamide (C6H6ClNOS) is characterized by an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

4-Chlorobenzenesulfinamide (CAS 16096-86-9) is a high-purity analytical reference standard with the molecular formula C6H6ClNOS and a molecular weight of 175.64 g/mol.

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.
