The characteristics of this chemical are as follows: (1)#H bond acceptors: 0; (2)#H bond donors: 0; (3)#Freely Rotating Bonds: 0; (4)Polar Surface Area: 0; (5)Exact Mass: 158.925343; (6)MonoIsotopic Mass: 158.925343; (7)Heavy Atom Count: 1; (8)Covalently-Bonded Unit Count: 1.

When you are dealing with this chemical, you should be very cautious. For one thing, it is toxic which may at low levels cause damage to health. If by inhalation, in contact with skin and if swallowed, it will be very dangerous. For another thing, it is highly flammable which may catch fire in contact with air, only needing brief contact with an ignition source, and it has a very low flash point or evolve highly flammable gases in contact with water.

Therefore, you should take the following instructions. Wear suitable protective clothing, gloves and eye/face protection. If in case of contact with eyes, rinse immediately with plenty of water and seek medical advice and if in case of accident or if you feel unwell, seek medical advice immediately (show the label whenever possible.) Then avoid contacting with skin and eyes, but if contact with skin, wash immediately with plenty of soap-suds. When comes to its storage, take precautionary measures against static discharges and keep it away from sources of ignition.
