1,4-dioxacycloheptadecane-5,17-dione

Endpoint summary

Additional information

The substance is a clear colourless viscous liquid at ambient temperature, with very low volatility. In water, it is slightly soluble, with no dissociation anticipated, and should not display surface-active properties.

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