Chemical Structure

3,6-dichloro-1$l^{6},2-benzothiazole-1,1-dione CAS 15864-53-6 chemical structure

Description

The occurrence of 3,6-dichloro-1$l^{6},2-benzothiazole-1,1-dione is closely related to an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

3,6-dichloro-1$l^{6},2-benzothiazole-1,1-dione (CAS 15864-53-6), molecular formula C7H3Cl2NO2S and molecular weight 236.08 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 3,6-dichloro-1$l^{6},2-benzothiazole-1,1-dione (C7H3Cl2NO2S) is characterized by an amide group, a sulfone group, a carboxylic acid group, 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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.

CATO manufactures 3,6-dichloro-1$l^{6},2-benzothiazole-1,1-dione under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
