2,2-Dichloropropionic acid is the organic compound with the formula CH3CCl2CO2H.[1] A colorless liquid, it once was marketed under the name Dalapon as a selective herbicide used to control perennial grasses. The major use of dalapon was on food crops including sugarcane and sugar beets.[2]
Regulation[]
Its use is no longer authorized in France.[3]
The National Institute for Occupational Safety and Health in the United States has identified it as a potential workplace hazard. The recommended time-weighted average exposure limit is 6 milligrams per cubic meter during a 10-hour workday.[4]
