2Heptanone

2-Heptanone, also known as methyl n-amyl ketone (MNAK), is an organic compound with the chemical formula C7H14O. It is a colorless liquid with a fruity, banana-like odor. It belongs to the ketone family of organic compounds, characterized by a carbonyl group (C=O) bonded to two alkyl groups. In the case of 2-heptanone, the carbonyl group is at the second position of a seven-carbon chain.

This compound is soluble in most organic solvents but has limited solubility in water. Its boiling point is approximately 144 degrees Celsius. 2-Heptanone is produced industrially through the oxidation of 2-heptanol or by the reaction of butanal with propyl magnesium bromide followed by oxidation.

2-Heptanone finds applications as a solvent in various industries. It is used as a solvent for lacquers, resins, and cellulose derivatives. Its moderate evaporation rate makes it suitable for coatings and inks. It also serves as a fragrance ingredient in perfumes and cosmetics due to its pleasant scent. Additionally, it can be used as an intermediate in the synthesis of other organic chemicals. While generally considered to have low toxicity, prolonged or excessive exposure can cause irritation to the eyes, skin, and respiratory tract.
