Isopropyl nitrate (IPN, 2-propyl nitrate) is a coloreless liquid monopropellant. It is used as a diesel cetane improver. IPN is a low-sensitivity explosive, with a detonation velocity of approximately 5400 m/s.
Isopropyl nitrate was previously used in a jet engine starting system, primarily by the RAF, and was known as AVPIN. It has also been used as a fuel for power supply and actuation in guided weapons, notably in the British Royal Navy.[1]
