Chemical Structure
Description
The occurrence of 2-(2,5-Dichlorophenoxy)propanoyl chloride is closely related to a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
2-(2,5-Dichlorophenoxy)propanoyl chloride (CAS 79239-50-2), molecular formula C9H7Cl3O2 and molecular weight 253.51 g/mol, is a CATO reference standard with documented purity and traceability.
2-(2,5-Dichlorophenoxy)propanoyl chloride (C9H7Cl3O2) contains a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system. Halogen substitution raises its density and boiling point, 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).
