Tris(phenylthio)methane CAS 4832-52-4

Description

The occurrence of Tris(phenylthio)methane is closely related to sulfur-containing functionality, a polycyclic aromatic system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

Tris(phenylthio)methane (CAS 4832-52-4), molecular formula C19H16S3 and molecular weight 340.53 g/mol, is a CATO reference standard with documented purity and traceability.

Tris(phenylthio)methane (C19H16S3) contains sulfur-containing functionality, a polycyclic aromatic system. 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.

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.
