Useful:

• Chemical Classes: Solvents -> Ketones (
• Canonical SMILES: CCCC(=O)C
• Inhalation Risk: A harmful contamination of the air will be reached rather slowly on evaporation of this substance at 20 °C.
• Effects of Short Term Exposure: The substance is irritating to the eyes, skin and respiratory tract. Exposure above the OEL could cause lowering of consciousness.
• Effects of Long Term Exposure: Repeated or prolonged contact with skin may cause dermatitis.
• 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.
