Chemical Structure
Description
Based on its molecular formula C7H8ClNO, 3-Chloro-4-Methoxyaniline contains an amide 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 157.60 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).
3-Chloro-4-Methoxyaniline (CAS 5345-54-0), molecular formula C7H8ClNO and molecular weight 157.60 g/mol, is a CATO reference standard with documented purity and traceability.
