1,3-Cyclohexadiene is a highly flammable cycloalkene that occurs as a colorless clear liquid. Its refractive index is 1.475 (20 °C, D).

It can be used as a hydrogen donor in transfer hydrogenation, since its conversion to benzene + hydrogen is in fact exothermic (-24.3 kJ/mol in the gas phase, as indicated by heats of hydrogenation).cite web|url=http://webbook.nist.gov/cgi/cbook.cgi?ID=C592574&Units=SI&Mask=8#Thermo-React|title=1,3-Cyclohexadiene|publisher=US National Institute of Standards and Technology|date=2007-04-13|accessdate=2007-04-13] cite web|url=http://webbook.nist.gov/cgi/cbook.cgi?ID=C71432&Units=SI&Mask=8&StartReac=50#Thermo-React|title=Benzene|publisher=US National Institute of Standards and Technology|date=2007-04-13|accessdate=2007-04-13] Despite this apparent instability with respect to benzene, the 1,3-cyclohexadiene motif is found in several natural products such as α-terpinene.
