Chlorinated diphenyl oxide is a white or yellowish waxy solid or very viscous liquid.

These materials are used as dielectric fluids in the electrical industry; they may be used as organic intermediates to make drugs and other chemicals; and in dry cleaning detergents. Used in the manufacture of flame-inhibiting polymers, as corrosion inhibitors, drycleaning detergents, thermal lubricants, additives for soaps and lotions, and in the manufacture of hydraulic fluids, pesticides, wood preservatives, and electric insulators.

If this chemical gets into the eyes, remove any contact lenses at once and irrigate immediately for at least 15 minutes, occasionally lifting upper and lower lids. Seek medical attention immediately. If this chemical contacts the skin, remove contaminated clothing and wash immediately with soap and water. Seek medical attention immediately. If this chemical has been inhaled, remove from exposure, begin rescue breathing (using universal precautions, including resuscitation mask) if breathing has stopped and CPR if heart action has stopped. Transfer promptly to a medical facility. When this chemical has been swallowed, get medical attention. Give large quantities of water and induce vomiting. Do not make an unconscious person vomit.

UN3082 Environmentally hazardous substances, liquid, n.o.s., Hazard class: 9; Labels: 9-Miscellaneous hazardous material, Technical Name Required. UN3077 Environmentally hazardous substances, solid, n.o.s., Hazard class: 9; Labels: 9-Miscellaneous hazardous material, Technical Name Required.

Incompatible with oxidizers (chlorates, nitrates, peroxides, permanganates, perchlorates, chlorine, bromine, fluorine, etc.); contact may cause fires or explosions. Keep away from alkaline materials, strong bases, strong acids, oxoacids, epoxides. May be able to form unstable peroxides. Reacts with aluminum.

For trichloro phenyl ether, solution in a flammable solvent and incineration in a furnace with afterburner and scrubber is recommended.

Chlorinated diphenyl oxide causes an acneform dermatitis (chloracne).
Limited experience with humans has shown that exposure to even small amounts of the higher chlorinated derivatives, particularly hexachlorodiphenyl oxide, may result in appreciable acneform dermatitis.1 Chloracne is usually persistent and affects the face, ears, neck, shoulders, arms, chest, and abdomen (especially around the umbilicus and on the scrotum). The most sensitive areas are below and to the outer side of the eye (malar crescent) and behind the ear.2 The skin is frequently dry with noninflammatory comedones and pale yellow cysts containing sebaceous matter and keratin.
