[2,2'-Bi[1,3]dithiolo[4,5-d][1,3]dithiolylidene]-5,5'-dione CAS 64394-47-4

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.

[2,2'-Bi[1,3]dithiolo[4,5-d][1,3]dithiolylidene]-5,5'-dione (CAS 64394-47-4) is a high-purity analytical reference standard with the molecular formula C8O2S8 and a molecular weight of 384.60 g/mol.

[2,2'-Bi[1,3]dithiolo[4,5-d][1,3]dithiolylidene]-5,5'-dione (C8O2S8) contains a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. The carboxyl group imparts weak acidity; 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.
