Chemically, it could be oxidized to acetone or bear numerous reactions to variety compounds like isopropoxides or aluminium isopropoxide. As an isopropyl team connected to a hydroxyl group (chemical formulation (CH3)2CHOH) it truly is The only example of a secondary alcohol, exactly where the alcohol carbon atom is hooked up to 2 other carbon atoms. It's really a structural isomer of propan-one-ol and ethyl methyl ether. They all provide the formula C3H8O.
