Used primarily as a chemical intermediate in the synthesis of other triazine-based compounds. It serves as a precursor in the production of dyes, optical brighteners, and fluorescent whitening agents for textiles and paper. Due to its high chlorine content and reactivity, it also finds use in specialized organic synthesis where chlorinated building blocks are required. Its stability under certain conditions makes it suitable for controlled release of trichloromethyl groups in research settings. Limited use in agrochemicals and polymer modification due to its reactivity and handling challenges.
