Chemical Structure
Description
Structurally, 4-Bromo-3-ethylaniline (C8H10BrN) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, bromine 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 200.08 g/mol, it falls into the medium-molecular-weight range. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
