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.
