Description of key information

Additional information

Physico-chemical properties of registered substance were determined from experimental testing, except Water solubility that was derived from a QSAR approach and that is supported by an experimental study. Some endpoints were waived, based on chemical structure.

The substance is a pale yellow liquid at ambient temperature, with low volatility. In water, it is slightly soluble, and slightly denser, so likely sink.

No surface-active properties is anticipated.

It has low potential for bioaccumulation.

It is not classified as hazardous with regard to physical hazards (flammability, explosivity, oxidising properties) based on CLP criteria.
