Used as an intermediate in the synthesis of pharmaceuticals, particularly in the production of antihypertensive drugs and other nitrogen-containing heterocyclic compounds. It serves as a building block in agrochemicals for developing herbicides and pesticides due to its ability to enhance selectivity and biological activity. Also employed in the preparation of dyes and functional materials where chloro and amino groups allow for further chemical modifications. Its reactivity makes it valuable in research and development of new active ingredients in both medicinal and agricultural chemistry.
