Chemical Structure
Description
4,6,7-Trichloro-1-methyl-3-oxo-1,3-dihydroisobenzofuran-5-carbonitrile (C10H4Cl3NO2) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine 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 high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
4,6,7-Trichloro-1-methyl-3-oxo-1,3-dihydroisobenzofuran-5-carbonitrile (CAS 194923-81-4), molecular formula C10H4Cl3NO2 and molecular weight 276.50 g/mol, is a CATO reference standard with documented purity and traceability.
