Why do Chemists have it.. To see to people like us?
Its used to sanitise surfaces from microbiological contamination thats why chemists have it. It also acts as a mild degreasant which is handy to use as a non toxic cleaner albiet a flammable one
It's propanol. Propan-2-ol to be precise. C3H8O.
Since it has 3 carbon atoms, rather than 2 for ethanol, or 1 for methanol, it has a higher boiling point and is less volatile.
To be more precise its an isomer of propanol, CH3CHOHCH3, versus the linear n-propanol which is CH3CH2CHOH 😉
And dont drink it, it might kill you.
