2-Propanol is a colourless highly flammable liquid with an odour resembling that of a mixture of ethanol and acetone. The compound is completely miscible with water, ethanol, acetone, chloroform, and benzene. Analytical methods are available for the detection of 2-propanol in various media (air, water, blood, serum, and urine) with detection limits for air, water, and blood of 2 x 10-5 mg/m3, 0.04 mg/litre, and 1 mg/litre, respectively. Gas chromatographic methods (primarily using flame ionization detection) as well as paper electrophoresis and photoionization ion mobility spectrometry methods are available for the determination of 2-propanol in the various media.
