There’s differece of opinion with alcohol. One school of jurisprudence goes by the ruling that it’s the fermentation part that makes it haram, so synthetically made ethanol in a lab isn’t haram if it’s not used in levels that intoxicate, whereas another school says it’s the actual intoxicating property of the chemical that’s haram so you can’t use it unless it’s for necessary medical reasons and there’s no alternative. I don’t know what the other two schools say.
