General description: | 1,2-Dichloropropane (1,2-D), is a colorless watery liquid with a sweet odor. It sinks in water and produces irritating vapor. It is a short-chain chlorinated aliphatic compound, commonly used as fumigant and as insecticide. It is a widespread groundwater contaminant. Anaerobic bacteria have the capacity to reductively dechlorinate it to propene. |
