Description and Uses
Dichlone is an obsolete foliar fungicide. It has a low aqueous solubility and is not mobile and, based on its chemical properties, it is unlikely to leach to groundwater. It is not persistent in most soil systems. Dichlone has a moderate mammalian toxicity. Little has been reported regarding its toxicity to biodiversity.
Use in textiles, as organic catalyst, as chemical intermediate, as additive in dye binders. Also used as an important catalyst to produce 3,3-dichlorobenzene.
