Chemical Structure
Description
The occurrence of Ethyl 2,5-dichloro-3-methylbenzoate 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.
Ethyl 2,5-dichloro-3-methylbenzoate (CAS 1806346-80-4), molecular formula C10H10Cl2O2 and molecular weight 233.09 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C10H10Cl2O2, Ethyl 2,5-dichloro-3-methylbenzoate contains a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 233.09 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
