Used primarily in biochemical research, this compound serves as an inhibitor of phenylalanine hydroxylase, an enzyme involved in the metabolism of phenylalanine. By inhibiting this enzyme, it helps in studying the biochemical pathways related to phenylalanine and tyrosine metabolism, which are crucial in understanding metabolic disorders like phenylketonuria (PKU). Additionally, it is utilized in the synthesis of various peptides and amino acid derivatives, aiding in the development of pharmaceuticals and therapeutic agents. Its role in research extends to neuroscience, where it helps in exploring neurotransmitter synthesis and function, particularly those involving dopamine and norepinephrine.
