| Hazard Information | Back Directory | [Description]
Dimefuron is a herbicide used for the control of annual broadleaved weeds. It has a moderate aqueous solubility and a low volatility. It may be persistent in soil and aquatic systems depending on local conditions. Based on its physico-chemical properties it has potential to leach to groundwater. It is highly toxic to algae, moderately toxic to earthworms but appears to be less toxic to other organisms for which data is available. Dimefuron has a low oral mammalian toxicity. | [Uses]
Dimefuron is a pesticide residue in the muscles and liver tissues of different fishes. | [Definition]
ChEBI: Dimefuron is a member of ureas. | [Production Methods]
The commercial production of dimefuron involves a multi-step chemical process starting with the reaction of 3,3-dimethylurea with phosgene or a phosgene equivalent to form an intermediate, followed by condensation with a benzofuran derivative under controlled conditions. The reaction occurs in an organic solvent, with temperature and pH carefully monitored to maximize yield and purity. The crude dimefuron is purified via filtration and recrystallisation to remove impurities and formulated. | [Mechanism of action]
Selective, absorbed mainly through the roots. Photosystem II inhibitor. | [Pesticide Type]
