  • Applications

    Mirex (CAS 2385-85-5) is a legacy organochlorine insecticide historically used for termite and other structural pest control, including soil-termite treatments and urban ant management; it has also been evaluated as a flame-retardant additive in polymers and coatings; in addition, due to its persistence and potential for bioaccumulation, Mirex has been the subject of environmental fate studies and regulatory assessments, making it a focus in environmental science and materials formulation.
