Chemical Structure
Description
The occurrence of 2,7-Dichlorothianthrene is closely related to sulfur-containing functionality, chlorine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
2,7-Dichlorothianthrene (CAS 60420-80-6) is a high-purity analytical reference standard with the molecular formula C12H6Cl2S2 and a molecular weight of 285.21 g/mol.
Owing to sulfur-containing functionality, chlorine substitution, an aromatic ring system, 2,7-Dichlorothianthrene is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 285.21 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO manufactures 2,7-Dichlorothianthrene under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
