Chemical Structure
Description
3-[(2,6-Dichlorophenyl)methyl]-2,4-dihydroxybenzaldehyde (C14H10Cl2O3) contains a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, a polycyclic aromatic system. 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.
3-[(2,6-Dichlorophenyl)methyl]-2,4-dihydroxybenzaldehyde (CAS 339106-82-0), molecular formula C14H10Cl2O3 and molecular weight 297.13 g/mol, is a CATO reference standard with documented purity and traceability.
