Chemical Structure

4,4´,Dimethyl-5,5'-diphenyltetrathiafulvalene CAS 56851-13-9 chemical structure

Description

The occurrence of 4,4´,Dimethyl-5,5'-diphenyltetrathiafulvalene is closely related to sulfur-containing functionality, a polycyclic aromatic system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

4,4´,Dimethyl-5,5'-diphenyltetrathiafulvalene (CAS 56851-13-9), molecular formula C20H16S4 and molecular weight 384.60 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, 4,4´,Dimethyl-5,5'-diphenyltetrathiafulvalene (C20H16S4) contains sulfur-containing functionality, a polycyclic aromatic system. The molecule exhibits a degree of unsaturation (DBE) of 13.0, corresponding to approximately 13 ring(s) or double-bond equivalent(s). With a molecular weight of 384.60 g/mol, it falls into the moderately-high-molecular-weight range. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

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.
