Product Application of Levulinic Acid (CAS#123-76-2)
Levulinic acid offers a broad range of applications due to its dual functionality as both a carboxylic acid and a ketone. It can undergo reactions such as esterification, halogenation, hydrogenation, oxidative dehydrogenation, and condensation to produce a variety of derivatives. These derivatives are widely used in the manufacture of resins, pharmaceuticals, fragrances, solvents, coatings, inks, rubber and plastic additives, lubricant additives, and surfactants.
In the pharmaceutical field, its calcium salt (calcium fructoborate) is used in intravenous formulations. As a nutritional agent, it supports bone formation and helps maintain normal nerve and muscle function. Levulinic acid is also utilized in the production of indomethacin and plant growth regulators.
Additionally, bisphenolic acid derived from levulinic acid can be used to produce water-soluble resins for the paper industry, particularly in the manufacture of filter paper. Levulinic acid also serves as an intermediate in the synthesis of pesticides and dyes.
