Description and Uses

1,4-Dichlorobenzene (also known as p-dichlorobenzene) is a chlorinated aromatic compound with a distinctive aromatic odor that is very strong at high concentrations. It is a white or colorless crystal at room temperature (Akron 2009, HSDB 2009). 1,4-Dichlorobenzene is practically insoluble in water; soluble in chloroform, carbon disulfide, benzene, and ether; and very soluble in ethanol and acetone. 1,4-Dichlorobenzene is noncorrosive, volatile, and combustible, and it is flammable when exposed to heat, flame, or oxidizers. When it is heated to decomposition, toxic gases and vapors (such as hydrochloric acid and carbon monoxide) are released (HSDB 2009). It is stable at room temperature under normal handling and storage in closed containers (Akron 2009).
1,4-Dichlorobenzene is the primary ingredient in mothballs and deodorant cakes placed in toilet bowls, urinals, and animal holding facilities. People may also use it to control lice and mites in and around birdcages. 1,4-Dichlorobenzene is used as an insecticide on fruit and is used to control mold and mildew growth on tobacco seeds, leather, and certain fabrics. It is also approved for controlling wax moths in empty, stored beehives.

1,4-Dichlorobenzene is used to make mothballs and solid deodorant blocks for garbage cans and restrooms. It is also used to control odors in places where animals are held. It has been used as an insecticide on fruit, and to control mold and mildew on tobacco seeds, leather and some fabrics. 1,4-Dichlorobenzene is sent into the air by plants that make or use it and a small amount is released to soil and water. This chemical can also be detected in indoor air where products containing 1,4-Dichlorobenzene are used.
