1,3-Dichloropropene

1,3-Dichloropropene, sold under diverse trade names, is an organochlorine compound with the formula C3H4Cl2.

In the US, the Department of Health and Human Services (DHHS) has determined that 1,3-dichloropropene may reasonably be anticipated to be a carcinogen.

In California, the Office of Environmental Health Hazard Assessment has determined that 1,3-dichloropropene is a carcinogen, and in 2022 established a No Significant Risk Level (NSRL) of 3.7 micrograms/day.

[9] The International Agency for Research on Cancer (IARC) has determined that 1,3-dichloropropene is possibly carcinogenic to humans.

[11] Under the brand name Telone, 1,3-D was one of Dow AgroSciences's products until the merger into DowDuPont.

NFPA 704 four-colored diamond Health 2: Intense or continued but not chronic exposure could cause temporary incapacitation or possible residual injury. E.g. chloroform Flammability 3: Liquids and solids that can be ignited under almost all ambient temperature conditions. Flash point between 23 and 38 °C (73 and 100 °F). E.g. gasoline Instability 0: Normally stable, even under fire exposure conditions, and is not reactive with water. E.g. liquid nitrogen Special hazards (white): no code
