Test material

Constituent 1
Chemical structure
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
Test material form:
other: Liquid
Details on test material:
Please note that although the substance is stated as the mono-constituent substance 2-(6-methyl-8-(-1-methylethyl)bicyclo(2.2.2)oct-5-en-2(3)-yl-1,3-dioxolane in the report, analytical data on the same batch shows that the test substance is in fact the multi-constituent substance Reaction mass of 2-(7-isopropyl-5(6)-methylbicyclo[2.2.2]oct-5-en-2-yl)-1,3-dioxolane and 2-(8-isopropyl-5(6)-methylbicyclo[2.2.2]oct-5-en-2-yl)-1,3-dioxolane.
