Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of antiviral and antibacterial agents. Its structure allows for easy functionalization, making it valuable in medicinal chemistry for constructing nitrogen-containing heterocyclic compounds. Also employed in the preparation of agrochemicals, including herbicides and plant growth regulators, due to its reactivity and ability to enhance bioactivity. Additionally, it serves as a building block in the creation of dyes and functional materials where chlorine and amino groups participate in coupling reactions.
