Chemical Structure
Description
Structurally, 1-(4-Aminophenyl)ethan-1-one hydrochloride (C8H9NOHCl) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 4.0, corresponding to approximately 4 ring(s) or double-bond equivalent(s). With a molecular weight of 171.62 g/mol, it falls into the medium-molecular-weight range. 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).
1-(4-Aminophenyl)ethan-1-one hydrochloride (CAS 41784-08-1), molecular formula C8H9NOHCl and molecular weight 171.62 g/mol, is a CATO reference standard with documented purity and traceability.
