General description

Isopropyl Alcohol or 2-Propanol is a very commonly used disinfectant within pharmaceutical companies, hospitals and cleanrooms. It is even used in the purification of electronics and medical device manufacture. It has a number of different purity grades and they are designed for different use. They are beneficial cleaning chemicals and disinfectants, and depending on how concentrated they are, they can get rid of all sorts of bacteria and impurities.

2-Propanol is a secondary alcohol. It has been tested as a substitute fuel for use in various fuel cells. CuO powder dissolved in 2-propanol has been used for the laser ablation assisted synthesis of Cu colloids. Suspension of 2-propanol with Zn(NO3)2 has been employed for the fabrication of titanium dioxide-coated stainless steel (P25-TiO2/SS) photoanode coated with a uniformly thick layer of P25-TiO2. This photoanode was used for the electrochemical photocatalytic (ECPC) degradation process

70% Isopropyl Alcohol (IPA 70)

Between the concentrations of 60% and 90%, Isopropyl alcohol is a very effective agent against microbial bacteria, fungi, and viruses. Higher concentrations don’t generate a much more desirable effectiveness against bacteria, fungi and viruses. This is because, there has to be a significant enough presence of water with the Isopropyl alcohol in order to be effective. And this percentage of water needs to be at least more than 10% within the solution. And the mixture of 30% water with 70% Isopropyl alcohol works best.

The reason water is so important is because it acts as a catalyst and has a major role in denaturing the proteins of cell membranes of vegetative cells. 70% IPA solutions are very effective in breaching the cell wall fully. Also, the presence of water slows down evaporation and increases the surface contact time with the membrane. With 91% IPA, the evaporation is instant and protein coagulates, rendering the effect of the IPA greatly reduced.


2-propanol may be used in the synthesis of methyl isobutyl ketone with satisfactory yield in the presence of bifunctional Cu-base catalysts. It can undergo oxidation in the presence of titanium oxide-supported manganese oxide to form acetone. 2-Propanol (Isopropanol) has been used for isolation and quantitative determination of carotenes and xanthophyll from Capsicum annum pericarp extracts by HPLC. It has been used as solvent in the dissolution of Pt and TiO2 precursors, for the fabrication of Pt-TiO2/Ti electrodes.
