CAS 18999-28-5: 2-Heptenoic acid
Description:2-Heptenoic acid is an unsaturated fatty acid characterized by a double bond located at the second carbon of the heptanoic acid chain. Its molecular formula is C7H12O2, and it features a carboxylic acid functional group, which imparts acidic properties. This compound is typically a colorless to pale yellow liquid with a distinctive odor. It is soluble in organic solvents and exhibits limited solubility in water due to its hydrophobic hydrocarbon chain. The presence of the double bond contributes to its reactivity, making it susceptible to various chemical reactions, such as hydrogenation and oxidation. 2-Heptenoic acid can be used in organic synthesis and may serve as an intermediate in the production of various chemicals, including surfactants and plasticizers. Additionally, it may have applications in flavor and fragrance industries due to its unique scent profile. As with many unsaturated fatty acids, it is important to handle 2-heptenoic acid with care, as it can be irritating to the skin and eyes.
