Used in pharmaceutical research as a key intermediate in the synthesis of biologically active compounds, particularly those targeting neurological and metabolic pathways. It serves as a building block for pyrrole-containing molecules with potential antidepressant, anti-inflammatory, or neuroprotective properties. Also explored in the development of enzyme inhibitors due to its structural similarity to endogenous neurotransmitters and cofactors. Its functional groups allow for easy modification in drug design and optimization.
