Chemical Structure
Description
Methyl 2-((4-(2,4-dichlorophenyl)-1,2,3-thiadiazol-5-yl)thio)acetate (CAS 338409-08-8), molecular formula C11H8Cl2N2O2S2 and molecular weight 335.23 g/mol, is a CATO reference standard with documented purity and traceability.
Methyl 2-((4-(2,4-dichlorophenyl)-1,2,3-thiadiazol-5-yl)thio)acetate (C11H8Cl2N2O2S2) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
