Solubility in water 1.8mg/L(25℃);Solubility in other solvents(25℃,kg/kg):Acetone9.1,Dichloromethane7.1,Methanol0.98,Xylene4.6,Chlorobenzene5.6.Hydrolyzed by DT5080d(pH 5~9,35℃). Flash point 46.7°C. | | Uses | Herbicide. | | Production Methods | Tridiphane is commercially synthesised through a multi-step organic process that centres on constructing its oxirane (epoxide) ring and attaching the two key substituents: a 3,5-dichlorophenyl group and a 2,2,2-trichloroethyl group. The production typically begins with the preparation of the appropriate halogenated aromatic and aliphatic precursors, which are then coupled through nucleophilic substitution or halogenation reactions. The final step involves epoxidation to form the oxirane ring, yielding the active tridiphane molecule. | | Definition | ChEBI: Tridiphane is a dichlorobenzene. | | Mechanism of action | Enzyme inhibitor - inhibits meristematic activity | | Safety Profile | Poison by ingestion andintraperitoneal routes.
