PRODUCT INTRODUCTION
description
1,2-Dibromo-3-chloropropane is a manufactured chemical and is not found naturally in the environment. It is a colorless liquid with a sharp smell. It can be tasted in water at very low concentrations. Some industries use it to make another chemical that is used to make materials that resist burning. Large amounts of 1,2-dibromo-3-chloropropane were used in the past on certain farms to kill pests that harmed crops. Farmers in all states other than Hawaii stopped using this chemical in 1979. Hawaii stopped using it in 1985. We do not know exactly how much of it is currently made or used by industry, but it is probably a small amount.
