Chemical Structure

2,4,6-Trichlorobenzenethiol CAS 24207-66-7 chemical structure

Description

2,4,6-Trichlorobenzenethiol (CAS 24207-66-7), molecular formula C6H3Cl3S and molecular weight 213.51 g/mol, is a CATO reference standard with documented purity and traceability.

2,4,6-Trichlorobenzenethiol (C6H3Cl3S) 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).

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.
