Methyl 4-amino-3-(2-fluorophenyl)-2-thioxo-2,3-dihydrothiazole-5-carboxylate (CAS 689772-56-3) is a high-purity analytical reference standard with the molecular formula C11H9FN2O2S2 and a molecular weight of 284.33 g/mol.
Methyl 4-amino-3-(2-fluorophenyl)-2-thioxo-2,3-dihydrothiazole-5-carboxylate (C11H9FN2O2S2) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine substitution. It is notably hygroscopic, 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).
CATO manufactures Methyl 4-amino-3-(2-fluorophenyl)-2-thioxo-2,3-dihydrothiazole-5-carboxylate 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.
