Levulinic Acid CAS# 123-76-2

Good Solubility in Polar Solvents: Levulinic acid is easily soluble in water and many organic solvents, making it versatile for various formulations.

Low Solubility in Non-Polar Solvents: Insoluble in gasoline, kerosene, turpentine, and carbon tetrachloride, allowing selective application in specific chemical processes.

Thermal Stability: Resistant to decomposition under normal pressure distillation, ensuring stability during processing.

Convertible to γ-Lactone: When heated for extended periods, it loses water to form unsaturated γ-lactone, providing potential for further chemical transformations.

Product Description of Levulinic Acid CAS# 123-76-2

Levulinic acid is an organic chemical compound with the molecular formula C₅H₈O₃. It dissolves readily in water and several organic solvents, yet displays no solubility in gasoline, kerosene, turpentine and carbon tetrachloride. This material boasts excellent thermal stability and barely decomposes during atmospheric distillation. Upon prolonged heating, it undergoes dehydration to produce unsaturated γ-lactone, which opens up avenues for subsequent chemical derivatization.
