Levulinic acid(or 4-oxopentanoic acid), is a 5-carbon carboxylic acid derived from the acid-catalysed degradation of glucose and other hexoses. It can be inhibitory to fermentation and enzymatic hydrolysis but can also be a valuable platform chemical from which a wide variety of chemicals, that can substitute for petroleum-derived products, can be derived. It is a versatile platform chemical due to its particular chemistry - it has two highly reactive functional groups (carboxyl and ketone) that allow a great number of synthetic transformations. The United States Department of Energy recognised levulinic acid as one of the top 12 value added chemicals to be derived from biomass.
One derivative of levulinic acid is gamma-Valerloactone, which we can also quantify using our ion chromatography system as well as by using our our GC-MS system.
