Cis-propiconazole (Ref: CGA 93950) |
Last updated: 24/08/2024 |
(Also known as: propiconazole II) |
SUMMARY |
Cis-propiconazole refers to a mixture of the two propiconazole cis-isomers 2R,4S and 2S,4R. It is moderately soluble in water and is not considered volatile. Little data is available for this specific isomer. However, technical propiconazole is moderately persistent in soil and aquatic systems with a low risk of leaching to groundwater. It tends to be moderately toxic to biodiversity. It has a moderate mammalian toxicity. |
Data alerts |
The following alerts are based on the data in the tables below. An absence of an alert does not imply the substance has no implications for human health, biodiversity or the environment but just that we do not have the data to form a judgement.
