Also known as 1,2-dihydrobenzene, 1,3-CHD
Cyclohexa-1,3-diene is an organic compound with the formula (C2H4)(CH)4. It is a colorless, flammable liquid. Its refractive index is 1.475 (20 °C, D). It is one of two isomers of cyclohexadiene, the other being 1,4-cyclohexadiene. It is commonly referred to as "benzane" due to the structural similarities to benzene and benzyne.
