'''Ethyl Alcohol''', chemical formula '''CH<sub>3</sub>CH<sub>2</sub>OH''', sometimes simply known as '''Alcohol''', is a drug used by both [[human]]s and [[San'Shyuum]].

==Overview==
Ethanol is a flammable, colorless, mildly toxic chemical compound with a distinctive perfume-like odor, and is the alcohol found in alcoholic beverages. It is also known as EtOH, using the common organic chemistry notation of representing the ethyl group (C<sub>2</sub>H<sub>5</sub>) with Et. Ethanol is a straight-chain alcohol, and its molecular formula is C<sub>2</sub>H<sub>5</sub>OH. An alternative notation is CH<sub>3</sub>-CH<sub>2</sub>-OH, which indicates that the carbon of a methyl group (CH<sub>3</sub>-) is attached to the carbon of a methylene group (-CH<sub>2</sub>-), which is attached to the oxygen of a hydroxyl group (-OH). Its empirical formula is C<sub>2</sub>H<sub>6</sub>O, a formula that it shares with dimethyl ether.

==Application==
It has several medicinal uses, but is most well known for its intoxicating effects (it can be used as a depressant), and as such is used in a wide variety of alcoholic beverages, for example, the ancient human beverage [[List of food and drinks|beer]] is a standard drug carried aboard [[UNSC]] starships and facilities. It has a number of medical uses as well. While these were never specifically mentioned, historical earth armies used ethyl alcohol (and alcoholic beverages) as an antiseptic and general anaesthetic. This being so, it is very possible the UNSC continues this use when better alternatives are unavailable. The [[Covenant]] also possessed alcohol or a very similar intoxicant.<ref>'''[[Halo: Contact Harvest]]'''</ref>

Ethanol is used in UNSC commercial vehicles as a biofuel, notably more advanced variants of the [[Jotun Heavy Industries|JOTUN]] series of agricultural drones.<ref>'''Halo: Contact Harvest''', ''page 212''</ref> It is likely that this was [[Wikipedia:Corn ethanol|corn ethanol]], a derivative of corn used as an alternative fuel. [[Corporal]] [[Locklear]] was very aware of these facts, and managed to find the Medicinal Grade MED34-CH3CH2OH alcohol stores on the {{UNSCShip|Gettysburg}} shortly before his death in the explosion of the [[Forerunner crystal]].<ref>'''[[Halo: First Strike]]''', ''page 283''</ref>

==Trivia==
*The [[Prophet of Regret]], then the [[Prophet of Regret|Vice Minister of Tranquility]], once showed up drunk to a meeting with the [[Prophet of Truth|Minister of Fortitude]].<ref>'''Halo: Contact Harvest''', ''page 263''</ref>
*The San'Shyuum, and probably other species, drink a liquid to purge their bloodstream to make them sober when drunk.<ref>'''Halo: Contact Harvest'''</ref>
