Used primarily as an intermediate in the synthesis of flame retardants and specialty polymers. It plays a key role in the production of cyclododecanone-based derivatives that enhance thermal stability and fire resistance in plastics and textiles. Its reactive chlorine groups allow for further chemical modifications, making it valuable in agrochemical and pharmaceutical research for building complex cyclic structures. Due to its ketone functionality, it also serves in condensation reactions and ring-expansion processes for advanced organic synthesis.
