Beschreibung

Allgemeine Beschreibung

Levulinic acid (LA), is a biogenic product of hexose acid hydrolysis, produced from renewable or bio-based resources. LA is reported to react with a variety of compounds to result in products, which are widely used in pharmaceuticals, personal care products, electronics, plasticizers, antifouling compounds, fuels, solvents, polymers, anti-freeze agents, batteries, coatings, biologically active materials, corrosion inhibitors, adsorbents, etc. LA is also employed as a chemical intermediate in the production of biodegradable polymers, fuel extenders, herbicides, flavors, antibiotics and useful 5-carbon compounds.

This substance is listed on the positive list of the EU regulation 10/2011 for plastics intended to come into contact with food. Find all available reference materials for compounds listed in 10/2011 here

Anwendung

Levulinic acid may be used as an analytical reference standard
for the quantification of the analyte in the following:

• Soy sauce using liquid chromatography coupled to mass spectrometry (LC–MS).
• Liquid food samples using gas chromatography with flame ionization detection (GC-FID).
