2-(1,3-Dithiol-2-ylidene)-5H-[1,3]dithiolo[4,5-c]pyrrole CAS 753478-52-3

Description

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.

2-(1,3-Dithiol-2-ylidene)-5H-[1,3]dithiolo[4,5-c]pyrrole (CAS 753478-52-3) is a high-purity analytical reference standard with the molecular formula C8H5NS4 and a molecular weight of 243.39 g/mol.

Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality, 2-(1,3-Dithiol-2-ylidene)-5H-[1,3]dithiolo[4,5-c]pyrrole is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 243.39 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
