The properties of this chemical are as followings：(1)ACD/BCF (pH 5.5): 1225.94 ; (2)ACD/BCF (pH 7.4): 1225.94 ; (3)ACD/KOC (pH 5.5): 5653.62 ; (4)ACD/KOC (pH 7.4): 5653.62 ; (5)Index of Refraction: 1.483 ; (6)Molar Refractivity: 43.76 cm³ ; (7)Molar Volume: 153 cm³ ; (8)Polarizability: 17.34 ×10^-24cm³ ; (9)Surface Tension: 27 dyne/cm ; (10)Density: 0.88 g/cm³ ; (11)Flash Point: 34.9 °C ; (12)Enthalpy of Vaporization: 37.9 kJ/mol ; (13)Boiling Point: 158.6 °C at 760 mmHg ; (14)Vapour Pressure: 3.38 mmHg at 25°C .

It is a kind of white crystalline solid with low melting and is insoluble in water while soluble in ether. And its product categories are including Pharmaceutical Intermediates;Bicyclic Monoterpenes;Biochemistry;Terpenes;Alpha Sort;C;CA -CG;CAlphabetic;Volatiles/ Semivolatiles;Acyclic;Alkenes;Organic Building Blocks.

Being a kind of highly flammable chemicals, it may catch fire in contact with air, only needing brief contact with an ignition source. Besides, it has a very low flash point or evolves highly flammable gases in contact with water. So you should be very careful while dealing with this chemical. Keep away from sources of ignition - No smoking and take precautionary measures against static discharges.

As for its usage, it could be applied in composing camphor, spice( such as acetic acid bornyl acetate),insecticide(such as toxaphene and isobornyl thiocyanoacetate), borneol and isobornyl acetate , etc.

In addition, you could convert the following datas into the molecular structure:
SMILES:C1(=C)\C(C)(C)C2CC1CC2
InChI:InChI=1/C10H16/c1-7-8-4-5-9(6-8)10(7,2)3/h8-9H,1,4-6H2,2-3H3
