Used as an intermediate in the synthesis of pharmaceuticals, particularly in the production of antihypertensive drugs and other biologically active compounds. It serves as a building block in agrochemicals for developing herbicides and insecticides due to its ability to enhance selectivity and efficacy. Also employed in the manufacture of dyes and functional materials where nitrogen-containing heterocycles improve stability and performance. Its chloro and methyl functional groups allow for further chemical modifications, making it valuable in research and development of new chemical entities.
