* [[Aerozine 50]] + [[nitrogen tetroxide]] (NTO) is widely used in historical American rockets, including the Titan II and all engines in the [[Apollo Lunar Module]]. Aerozine 50 is a mixture of 50% UDMH and 50% straight hydrazine (N<sub>2</sub>H<sub>4</sub>).<ref name="Ignition"/>{{rp|45}}
* Monomethylhydrazine (MMH) + NTO is used in smaller engines and reaction control thrusters: [[Apollo command and service module]] [[Reaction_control_system|RCS]],<ref>{{cite book

* [[Triethylborane]]/[[triethylaluminium]] (TEA-TEB) + [[liquid oxygen]] is used during the ignition process of some rocket engines that use liquid oxygen, used by the [[Merlin (rocket engine family)|SpaceX Merlin Engine Family]] and [[Rocketdyne F-1]].
* UDMH + NTO is frequently used by [[Roscosmos]], such as in the [[Proton (rocket family)]], and supplied by them to France for the Ariane 1 first and second stages (replaced with [[UH 25]]) and [[Indian Space Research Organisation|ISRO]] rockets using [[Vikas (rocket engine)|Vikas engine]].<ref>{{Cite web|url=http://www.hindu.com/2001/12/03/stories/2001120300481300.htm|archive-url=https://web.archive.org/web/20140323164318/http://www.hindu.com/2001/12/03/stories/2001120300481300.htm|url-status=dead|archive-date=2014-03-23|title=ISRO tests Vikas engine|date=2014-03-23|work=[[The Hindu]]|access-date=2019-07-29}}</ref>
