Chemical Structure
Description
The occurrence of 3-Fluoro-4-(4-methyl-1-piperazinyl)aniline is closely related to a nitrogen-containing heterocyclic scaffold, a nitrile group, fluorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
3-Fluoro-4-(4-methyl-1-piperazinyl)aniline (CAS 221198-99-8), molecular formula C11H16FN3 and molecular weight 209.26 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, fluorine substitution, 3-Fluoro-4-(4-methyl-1-piperazinyl)aniline is typically off-white to pale yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 209.26 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
