3-Ethyl-2,4-pentanedione

Description:
3-Ethyl-2,4-pentanedione, also known as ethyl acetoacetate, is an organic compound characterized by its diketone functional groups. It features a five-carbon chain with two carbonyl groups located at the second and fourth positions, along with an ethyl substituent at the third carbon. This compound is typically a colorless to pale yellow liquid with a sweet, fruity odor. It is soluble in organic solvents such as ethanol and ether but has limited solubility in water due to its hydrophobic alkyl groups. 3-Ethyl-2,4-pentanedione is known for its reactivity, particularly in condensation reactions, making it useful in organic synthesis, including the production of various pharmaceuticals and agrochemicals. Additionally, it can act as a chelating agent for metal ions, which enhances its utility in coordination chemistry. Safety considerations include handling it in a well-ventilated area and using appropriate personal protective equipment, as it may cause irritation to the skin and eyes.
