Dichlorobenzenes
CAS ID #: 95-50-1, 541-73-1, 106-46-7
Affected Organ Systems: Dermal (Skin), Developmental (effects during periods when organs are developing) , Hepatic (Liver), Ocular (Eyes), Renal (Urinary System or Kidneys)
Cancer Classification: NTP: Reasonably anticipated to be a human carcinogen
Please contact NTP, IARC, or EPA’s IRIS Hotline with questions on cancer and cancer classification.
Chemical Classification: Volatile organic compoundsSummary: 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.

Toxicological and Health Professionals
Succinctly characterizes the toxicologic and adverse health effects information for a hazardous substance.
Quick reference guide providing information such as chemical and physical properties, sources of exposure, routes of exposure, minimal risk levels, children's health, and health effects for a substance.
Prioritization of substances based on a combination of their frequency, toxicity, and potential for human exposure at National Priorities List (NPL) sites.
The MRL is an estimate of the daily human exposure to a hazardous substance that is likely to be without appreciable risk of adverse, non-cancer health effects over a specified duration of exposure. The information in this MRL serves as a screening tool to help public health professionals decide where to look more closely to evaluate possible risk of adverse health effects from human exposure.
