Chemical Structure
Description
2,4,5-Trichloro-1,3-benzothiazole (CAS 898747-87-0) is a high-purity analytical reference standard with the molecular formula C7H2Cl3NS and a molecular weight of 238.52 g/mol.
2,4,5-Trichloro-1,3-benzothiazole (C7H2Cl3NS) 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. 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 2,4,5-Trichloro-1,3-benzothiazole 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.
