Chemical Structure
Description
Structurally, 4-Chloro-2-fluorophenylhydrazine Hydrochloride (C6H6ClFN2HCl) contains a nitrile group, fluorine/chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 3.0, corresponding to approximately 3 ring(s) or double-bond equivalent(s). With a molecular weight of 197.03 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).
4-Chloro-2-fluorophenylhydrazine Hydrochloride (CAS 64172-78-7), molecular formula C6H6ClFN2HCl and molecular weight 197.03 g/mol, is a CATO reference standard with documented purity and traceability.
