Chemical Structure

4,4′-Thiodiphenylthiol CAS 19362-77-7 chemical structure

Description

The occurrence of 4,4′-Thiodiphenylthiol is closely related to sulfur-containing functionality in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies 4,4′-Thiodiphenylthiol (CAS 19362-77-7), a certified reference material (molecular formula C12H22S3, MW 262.50 g/mol) for analytical method development and quality control.

4,4′-Thiodiphenylthiol (C12H22S3) contains sulfur-containing functionality. Its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.

CATO manufactures 4,4′-Thiodiphenylthiol 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.
