Chemical Structure
Description
Structurally, (S)-1-((S)-2-Amino-4-methylpentanoyl)pyrrolidine-2-carboxylic acid compound with 2,2,2-trifluoroacetic acid (1:1) (C11H20N2O3C2HF3O2) contains an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine 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 342.31 g/mol, it falls into the moderately-high-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).
