Cyclohexene is a volatile liquid with a characteristic odour. It is a reactive cycloaliphatic alkene, as a building block used in several different markets, due to the functionality of the double bond which allows a range of chemistries to be applied, and downstream intermediates and products to be derived from it, such as the epoxide, diol and other useful downstream products. Cyclohexene is used in a diverse range of chemical synthesis. It is a building block used in Pharma(e.g. Clidanac, MK 346, Trandolapril) and Agchems such as Propargite. It also has industrial and consumer uses in the synthesis of waterproof coatings, LED encapsulation systems, crack resitant films, elastomers, tie binder for coatings, adhesives, silanes and as a precursor to the epoxides, diol and other useful downstream products.
