Chemical Structure
Description
1,3-dichloro-5-isothiocyanatobenzene (CAS 6590-93-8) is a high-purity analytical reference standard with the molecular formula C7H3Cl2NS and a molecular weight of 204.08 g/mol.
1,3-dichloro-5-isothiocyanatobenzene (C7H3Cl2NS) contains a nitrile group, 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 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).
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 1,3-dichloro-5-isothiocyanatobenzene 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.
