trans-2-Pentenoic acid

Description:

Trans-2-pentenoic acid is an unsaturated carboxylic acid characterized by a double bond between the second and third carbon atoms in its five-carbon chain, with the trans configuration indicating that the hydrogen atoms adjacent to the double bond are on opposite sides. This structural feature contributes to its unique physical and chemical properties. It is a colorless to pale yellow liquid with a pungent odor, and it is soluble in organic solvents while exhibiting limited solubility in water. The presence of the carboxylic acid functional group imparts acidic properties, allowing it to participate in various chemical reactions, such as esterification and oxidation. Trans-2-pentenoic acid can be used in organic synthesis and may serve as an intermediate in the production of other chemical compounds. Its reactivity is influenced by the double bond, making it susceptible to addition reactions. Safety considerations include handling it in well-ventilated areas and using appropriate personal protective equipment, as it may cause irritation upon contact with skin or eyes.

2-Pentenoic acid

CAS: 13991-37-2

2-Pentenoic acid is a fatty acid that belongs to the group of sodium salts. It is often used as a catalyst in organic synthesis. 2-Pentenoic acid has been shown to reduce the incidence of bowel disease and improve mitochondrial function. This compound is not toxic at doses up to 1 g/kg in mice, although it may cause acute toxicity at higher doses. 2-Pentenoic acid has also been shown to have anti-inflammatory properties that may be due to its ability to inhibit prostaglandin synthesis.
