Cyanoacetylene is an organic compound with formula C
3
HN
or H−C≡C−C≡N. It is the simplest cyanopolyyne. Cyanoacetylene has been detected by spectroscopic methods in interstellar clouds,[2] in the coma of comet Hale–Bopp and in the atmosphere of Saturn's moon Titan,[3] where it sometimes forms expansive fog-like clouds.[4]

Cyanoacetylene is one of the molecules that was produced in the Miller–Urey experiment. [5]
