Dichlorobenzenes

What are Dichlorobenzenes?

CAS#: 1,2-Dichlorobenzene CAS# 000095-50-1, 1,3-Dichlorobenzene CAS# 000541-73-1, 1,4-Dichlorobenzene CAS# 000106-46-7

There are three dichlorobenzene isomers- 1,2-dichlorobenzene, 1,3-dichlorobenzene, and 1,4-dichlorobenzene. Dichlorobenzenes do not occur naturally. 1,2-Dichlorobenzene is a colorless to pale yellow liquid used to make herbicides. 1,3- Dichlorobenzene is a colorless liquid used to make herbicides, insecticides, medicine, and dyes. 1,4-Dichlorobenzene, the most important of the three chemicals, is a colorless to white solid with a strong, pungent odor. When exposed to air, it slowly changes from a solid to a vapor. Most people can smell 1,4- dichlorobenzene in the air at very low levels.
