Description
CATO manufactures 3-Amino-4-phenylthiazole-2(3H)-thione 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.
3-Amino-4-phenylthiazole-2(3H)-thione (CAS 5316-81-4) is a high-purity analytical reference standard with the molecular formula C14H11BrClNO2 and a molecular weight of 340.60 g/mol.
3-Amino-4-phenylthiazole-2(3H)-thione (C14H11BrClNO2) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine/bromine substitution. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; 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.
