1,3-Dioxole, 2,2,4-trifluoro-5-(trifluoromethoxy)

Endpoint summary

Description of key information

Physico-chemical properties were determined from experimental testing. Some endpoints were waived, based on chemical structure or other properties.

The substance is a liquid at ambient temperature, with low boiling and high volatility.

In water, it is slightly soluble, denser, with no surface-active properties anticipated, and is expected to volatilise rapidly.

It is expected that the substance shows low potential for bioaccumulation, based on CLP criteria for aquatic chronic toxicity (log Kow<4).

It is classified as an extremely flammable liquid; no other physical hazards were identified, based on CLP criteria.
