Levulinic acid

CAS: 123-76-2

Levulinic acid is a dicarboxylic acid that is resistant to the formation of the levulinate ester. In vitro, it has been shown to have a synergistic effect with other antibiotics such as erythromycin and cefazolin against bacteria in experimental models. The mechanism of this synergistic effect is not known, but may be due to inhibition of bacterial cell wall synthesis. Levulinic acid can also be used as an injection solution or magnesium salt for surface methodology experiments. The rate of reaction with magnesium is slow, and the reactivity is similar to that of levulinate. Kinetic studies have shown that the rate-determining step in the reaction between levulinic acid and magnesium chloride is the binding of MgCl2 to LHA (levulinic acid). This binding also reacts slowly with water and formaldehyde.
