Used as an intermediate in the synthesis of pharmaceuticals, particularly in the production of beta-amino acid derivatives and active pharmaceutical ingredients (APIs) requiring chiral building blocks. Its ester and amino functional groups allow for versatile reactivity in coupling reactions, making it valuable in medicinal chemistry for developing drugs with specific stereochemistry. Commonly employed in the preparation of protease inhibitors and other bioactive molecules. Also utilized in the development of agrochemicals and fine chemicals where structurally constrained amino acid analogs are needed.
