| Hazard Information | Back Directory | [Description]
Dimepiperate is a rice herbicide that has a safening effect in rice especially against sulfonylurea herbicides. It has a moderate aqueous solubility and a low volatility. It is not expected to be persistent in soil systems, nor is it expected to leach to groundwaters. Dimepiperate is moderately toxic to fish but is less toxic to birds. it is moderately toxic to mammals if ingested and is an irritant. | [Chemical Properties]
Appearance like a waxy solid. mp38.8～39.3℃, bp164～168℃/99.75Pa, vapor pressure 0.53×10-3Pa (30℃), relative density 1.08 (25℃). | [Uses]
Dimepiperate is a systemic conduction type selective paddy herbicide. | [Definition]
ChEBI: Dimepiperate is a monothiocarbamic ester and a piperidinecarboxylate ester. | [Production Methods]
The commercial production of dimepiperate is a multi-step process. It typically involves the reaction of 1-methyl-1-phenylethanol with thiophosgene to form an intermediate, followed by coupling with piperidine under controlled conditions in an organic solvent. The reaction is optimised for yield and purity by maintaining specific temperature and pH levels. The crude dimepiperate is purified through distillation or recrystallisation to remove impurities. | [Mechanism of action]
Systemic, translocates upwards through plant. Inhibits lipid synthesis. | [Pesticide Type]
