2-Amino-3-(2-oxo-1,2-dihydroquinolin-4-yl)propanoic acid dihydrochloride

It combines an amino acid backbone with a quinolin-2-one moiety, making it valuable for constructing complex bioactive molecules where aromatic heterocycles are required. 2-Amino-3-(2-oxo-1,2-dihydroquinolin-4-yl)propanoic acid dihydrochloride is a heterocycle-substituted amino acid salt used strictly as a pharmaceutical intermediate.
