Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 4,6-dichlorobenzene-1,3-dithiol.
4,6-dichlorobenzene-1,3-dithiol (CAS 60822-12-0) is a high-purity analytical reference standard with the molecular formula C6H4Cl2S2 and a molecular weight of 211.13 g/mol.
4,6-dichlorobenzene-1,3-dithiol (C6H4Cl2S2) contains sulfur-containing functionality, chlorine substitution, an aromatic ring system. Halogen substitution raises its density and boiling point; 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
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.
