Used as an intermediate in the synthesis of pharmaceuticals, particularly in the production of certain antihypertensive drugs and other biologically active compounds. It plays a key role in the development of agrochemicals, including herbicides and pesticides, due to its ability to enhance selectivity and efficacy. Also employed in the manufacture of dyes and functional materials where nitrogen-containing heterocycles are required. Its structure allows for easy modification, making it valuable in research and development of new chemical entities.
