Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
4,5-Dichloro-benzothiazol-2-ylamine (CAS 1849-71-4) is a high-purity analytical reference standard with the molecular formula C7H4Cl2N2S and a molecular weight of 219.09 g/mol.
4,5-Dichloro-benzothiazol-2-ylamine (C7H4Cl2N2S) 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
CATO manufactures 4,5-Dichloro-benzothiazol-2-ylamine 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.
