:2-Pentenal
Description:
2-Pentenal, with the CAS number 764-39-6, is an unsaturated aldehyde characterized by a five-carbon chain with a double bond between the second and third carbon atoms and an aldehyde functional group at one end. Its molecular formula is C5H8O, and it typically appears as a colorless to pale yellow liquid with a distinctive, pungent odor. 2-Pentenal is known for its reactivity due to the presence of both the double bond and the aldehyde group, making it susceptible to various chemical reactions, including oxidation and polymerization. It is soluble in organic solvents and has limited solubility in water. This compound is used in organic synthesis and as an intermediate in the production of various chemicals, including flavoring agents and fragrances. Additionally, 2-pentenal can be involved in the formation of more complex molecules through reactions such as aldol condensation. Safety precautions should be taken when handling this substance, as it can be irritating to the skin and respiratory system.
