Used as a key building block in organic synthesis, particularly in the preparation of pharmaceuticals and agrochemicals. Its structure allows for easy functionalization, making it valuable in constructing nitrogen-containing compounds such as heterocycles. Commonly employed in the synthesis of beta-amino acids, peptides, and analogs of biologically active molecules. Also utilized in the production of dyes and specialty polymers due to its reactive amine and ester groups. Its versatility in condensation and substitution reactions enhances its role in medicinal chemistry research.
