It is a kind of transparent flammable liquid with good smelling. And it is stable and incompatible with strong oxidizing agents. Besides, it is insoluble with water but soluble in ethanol. Its categories are including biochemistry;monocyclic monoterpenes;terpenes;alphabetical listings;flavors and fragrances;i-l . As for its usage, it could be used in composing rubber and be used as the raw material of spice and also could be solvent.
Being the irritant chemicals, it may cause inflammation to the skin or other mucous membranes and may cause sensitization by skin contact, so you need to be very cautious while using it. Wear suitable gloves and avoid contact with skin. Besides, it is also dangerous for the environment, for it may present an immediate or delayed danger to one or more components of the environment. It is very toxic to aquatic organisms, and may cause long-term adverse effects in the aquatic environment. So while dealing with it, this material and its container must be disposed of as hazardous waste. And then avoid release to the environment and refer to special instructions/safety data sheet if necessary. Except all these, it is a very dangerous as it could mix with air to make explosion, so store it seperately with other flammable chemicals.
In addition, you could refer to the following datas to get the molecular structure:
