Used in biochemical research as a substrate for studying enzyme activity, particularly in the investigation of transaminases and other enzymes involved in amino acid metabolism. It serves as a precursor in the synthesis of various organic compounds, including heterocyclic molecules, which are important in pharmaceutical development. Additionally, it is employed in analytical chemistry for the detection and quantification of specific enzymes or metabolic pathways in biological samples. Its role in organic synthesis also extends to the preparation of intermediates for dyes and pigments.
