Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of antihypertensive drugs and other biologically active compounds. Its structure allows for easy functionalization, making it valuable in medicinal chemistry for building nitrogen-containing heterocycles. Commonly employed in coupling reactions and nucleophilic substitutions to form new carbon-nitrogen or carbon-carbon bonds. Also utilized in agrochemical research for designing herbicides and plant growth regulators due to its reactivity and stability under various reaction conditions.
