Chemical Structure

4-Chloro-1,3-benzenedithiol CAS 58593-78-5 chemical structure

Description

4-Chloro-1,3-benzenedithiol (C6H5ClS2) contains sulfur-containing functionality, chlorine substitution, an aromatic ring system. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

4-Chloro-1,3-benzenedithiol (CAS 58593-78-5) is a high-purity analytical reference standard with the molecular formula C6H5ClS2 and a molecular weight of 176.69 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.

As a certified reference material (CRM), 4-Chloro-1,3-benzenedithiol meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
