Test material
- Reference substance name:
- Reaction mass of 2-[7-isopropyl-5-methylbicyclo[2.2.2]oct-5-en-2-yl]-1,3-dioxolane and 2-[8-isopropyl-6-methylbicyclo[2.2.2]oct-5-en-2-yl]-1,3-dioxolane
- EC Number:
- 916-737-4
- Molecular formula:
- Reaction mass of 2-[7-isopropyl-5-methylbicyclo[2.2.2]oct-5-en-2-yl]-1,3-dioxolane and 2-[8-isopropyl-6-methylbicyclo[2.2.2]oct-5-en-2-yl]-1,3-dioxolane
- IUPAC Name:
- Reaction mass of 2-[7-isopropyl-5-methylbicyclo[2.2.2]oct-5-en-2-yl]-1,3-dioxolane and 2-[8-isopropyl-6-methylbicyclo[2.2.2]oct-5-en-2-yl]-1,3-dioxolane

Applicant's summary and conclusion
- Conclusions:
- The vapour pressure of the substance has been determined as 0.39 Pa at 25°C and 0.21 Pa at 20°C using the isothermal thermogravimetric effusion method (GLP-compliant study in accordance with EC A.4, OECD 104 and EPA OPPTS 830.7950).
