Acetone, Electronic/Cleanroom Grade also known as propanone, is an organic compound and a colorless, flammable liquid. Due to its miscibility with water, it serves as an important solvent. Used as a polar aprotic solvent in a wide range of organic reactions, acetone does not form an azeotrope with water. Thanks to it's low cost and volatility, it is also commonly used to clean laboratory glassware. Another characteristic of acetone is that it can be cooled with dry ice to -78 C without freezing.
