Used primarily as a chlorinating agent in organic synthesis, this compound facilitates the introduction of chlorine atoms into various substrates, making it valuable in the production of pharmaceuticals and agrochemicals. It also serves as a disinfectant and biocide due to its ability to release active chlorine, effective against bacteria, viruses, and fungi in water and surface treatments. Its stability and controlled reactivity allow for selective transformations in industrial processes, particularly where mild chlorination conditions are required.
