Used as an intermediate in organic synthesis, particularly in the preparation of heterocyclic compounds. It serves as a building block for pharmaceuticals and agrochemicals due to its reactive amino and cyano functional groups. Commonly employed in the synthesis of pyrimidines, pyridines, and other nitrogen-containing rings. Its tosylate group enhances solubility and stability in certain reaction conditions, making it valuable in multi-step synthetic routes. Also utilized in the development of dyes and functional materials where cyano ester derivatives are required.
