Used in biochemical research to study enzyme inhibition, particularly in relation to phenylalanine metabolism. It serves as a substrate analog to investigate the activity of enzymes like phenylalanine hydroxylase. Applied in neuroscience studies to explore neurotransmitter regulation and its impact on neurological disorders. Also utilized in the development of pharmaceuticals targeting metabolic and neurological conditions. Acts as a precursor in the synthesis of specialized compounds for therapeutic and diagnostic purposes.
