Isobutanol, also known as 2-methylpropan-1-ol or 2-methyl-1-propanol is an organic compound, an isomer of butanol it has the formula CH3CH(CH2)CH2OH.
Isobutanol will burn in open air, but due to its high flash point of 28 °C it will only ignite if heated prior.
Isobutanol is a colorless viscous liquid, with a strong characteristic odor. It is poorly soluble in water (8.7 mL/100 mL), but miscible with many organic solvents such as acetone or ethanol. It has a boiling point of 107.89 °C and a melting point of −108 °C.
Isobutanol is available at hardware stores as wood paint drying accelerator. Some products may also contain HCl, which require neutralization.
Isobutanol is much cheaper to buy that synthesize.
Isobutanol is the least toxic isomer of butanol. Its strong odor however may cause nausea or dizziness.
Should be stored in closed bottles away from any heat source.
Isobutanol can be safely burned.
