外観

白色～ほとんど白色粉末～結晶

化学的特性

White Solid

使用

Isoproturon may be used as a reference standard for the determination of isoproturon in crops using high performance liquid chromatography (HPLC) with fluorescence detection combined with UV decomposition and post-column derivatization.

定義

ChEBI: A member of the class of ureas that is 1,1-dimethylurea substituted by a p-cumenyl group at position 3. A selective, systemic herbicide used to control annual grasses and broadleaf weeds in cereals, its use within the EU has been banned after eptember 2017 on the grounds of potential groundwater contamination and risks to aquatic life; there have also been concerns about its endocrine-disrupting properties.

一般的な説明

Isoproturon is a phenylurea herbicide used to control ryegrass, silky bentgrass, and broadleaf species in spring and winter wheat.

危険性

Moderately toxic by ingestion, inhalation, and skin contact.

代謝経路

The major degradation product of isoproturon in most soil samples is identified as 2-hydroxyisoproturon, and the polar metabolites characterized are monodesmethylisoproturon and 2- hydroxymonodesmethylisoproturon. The detection of isoproturon in soil solution down to 170 cm depth and in creek water in concentrations exceeding 4 μg l^-1 and also of the polar metabolites in concentrations up to 0.9 μg l^-1 indicates the mobility of this phenylurea herbicide and its degradation products.
