Cannabidiol is insoluble in water but soluble in organic solvents such as pentane. At room temperature, it is a colorless crystalline solid.[33] In strongly basic media and the presence of air, it is oxidized to a quinone.[34] Under acidic conditions it cyclizes to THC,[35] which also occurs during pyrolysis (smoking).[36] The synthesis of cannabidiol has been accomplished by several research groups.[37][38][39]
