Chemical Structure
Description
Structurally, 1-Ethyl-N-((1-ethyl-5-fluoro-3-methyl-1H-pyrazol-4-yl)methyl)-5-methyl-1H-pyrazol-4-amine hydrochloride (C13H20FN5HCl) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, fluorine/chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 5.0, corresponding to approximately 5 ring(s) or double-bond equivalent(s). With a molecular weight of 301.79 g/mol, it falls into the moderately-high-molecular-weight range. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
