Used as an intermediate in the synthesis of dyes and optical brighteners, particularly in textile and paper industries. It plays a role in the production of reactive dyes due to its ability to form stable covalent bonds with cellulose fibers. Also employed in the development of agrochemicals and pharmaceuticals where triazine rings are needed for biological activity. Its chloro group is highly reactive, allowing easy substitution with nucleophiles like amines or alcohols, making it valuable in organic synthesis for building complex molecules.
