EC number: 213-243-4
CAS number: 931-87-3
is a cycloalkene with an eight-membered ring. Its most stable conformer
is shaped like a crown ether with alternating equatorial and axial
hydrogens very much like the chair conformation of cyclohexane.
is a colourless liquid with a mouldy odour at ambient temperature and
freezing point at 101 325 Pa: -15.8 ºC
point at 101 325 Pa: 145.6 ºC
density at 20 ºC: 0.8477
pressure (at 20 ºC): 9.9 hPa
coefficient n-octanol/water (Kow) at 25 ºC: log Kow = 5.0
solubility (20 ºC): 3 mg/l
activity is not a desired property of the material and is not expected
based on structure.
point at 101 325 Pa (Abel method, closed cup): 23.5 ºC
/ self-ignition temperature: 245 ºC at 100 200 Pa
on the chemical structure, the substance is incapable of reacting
exothermally with combustible materials.
stability of the substance is not considered to be critical.
significant dissociation is expected at environmental or physiological
pH values and beyond.
