α-Methyl-δ-valerolactone, with the CAS number 10603-03-9, is a cyclic ester belonging to the class of lactones. It is characterized by a five-membered ring structure that includes a methyl group at the alpha position relative to the carbonyl group. This compound is typically a colorless to pale yellow liquid with a pleasant odor, making it appealing for various applications. It is soluble in organic solvents and exhibits moderate polarity. The presence of the methyl group influences its physical properties, such as boiling point and viscosity, compared to other lactones. α-Methyl-δ-valerolactone is often utilized as a solvent, in the synthesis of polymers, and as an intermediate in organic synthesis. Additionally, it may have applications in the production of biodegradable materials due to its lactone structure, which can undergo ring-opening polymerization. Safety data indicates that, like many organic solvents, it should be handled with care, as it may cause irritation upon contact with skin or eyes.
