Used in the synthesis of nitrogen-containing heterocyclic compounds, particularly in pharmaceuticals and agrochemicals. Serves as a building block for bioactive molecules due to its reactive aldehyde and amino groups. Commonly employed in the development of kinase inhibitors and antimicrobial agents. Also utilized in coordination chemistry as a ligand precursor for metal-organic frameworks and catalysts. Its hydrochloride salt form enhances solubility and stability in synthetic processes.
