Widely used as an intermediate in the synthesis of dyes, pharmaceuticals, and agrochemicals. Its reactivity allows selective substitution of chlorine atoms, making it valuable in building complex organic molecules. Commonly employed in the preparation of triazine-based herbicides and antimicrobial agents. Also utilized in peptide coupling and as a linker in solid-phase organic synthesis due to its ability to form stable bonds with nucleophiles. Plays a role in the development of functional polymers and specialty chemicals where controlled reactivity is required.
