Product: ε-caprolactone
CAS#502-44-3
L-61049 is a colorless oily liquid with a special aroma of ester. Its molecule contains a five-membered lactone ring and an alkyl side chain. Since the carbonyl and epoxy groups on the lactone ring fix the structure of the molecule, the ε-caprolactone molecule exhibits strong stability and inertness. At the same time, the presence of alkyl side chains makes ε-caprolactone have better solubility and compatibility in solvents. Since the molecule of 6-caprolactone contains a carbonyl group, it has certain reactivity and can undergo various chemical reactions such as esterification, addition, and nucleophilic substitution.
