Description
2-Pentanone or methyl propyl ketone (MPK) is a colorless liquid ketone with the odor of fingernail polish or a strong fruity odor. It was found in apple and can be isolated from soya oil (Glycine max), pineapple and a few other plant sources. It also occurs naturally in tobacco and blue cheese as a metabolic product of Penicillium mold growth. It is a solvent of minor importance that can be used for cleaning or degreasing and becoming part of product formulation or mixture. It is also an industrial intermediate and can be used for paint additives and coating additives. It is sometimes used in very small amounts as a flavoring food additive.

Physical properties
Clear, colorless, very flammable liquid with a characteristic, pungent odor. An odor threshold
concentration of 20 ppbv was determined by a triangular odor bag method (Nagata and Takeuchi,
1990). Cometto-Mu?iz et al. (2000) reported nasal pungency threshold concentration ranging from
approximately 500 to 3,200 ppm.

Uses
2-Pentanone is used as a solvent for lacquers and surface coatings. It acts as a flavoring agent. It is also used as a solvent for cleaning and degreasing purpose. Further, it serves as an intermediate, paint additive and coating additive.
