Chemical Formula: C5H8O3
Synonyms:
MOQ (Minimum Order Quantity): 1 FCL (Full Container Load)
Appearance: Yellow Liquid
White flake crystals, hygroscopic. clear yellowish liquid after melting.It is easily soluble in water and alcohol, ether organic solvents.
Levulinic acid conventionally is derived from refined petroleum but technological advances now permit the production of levulinic acid from biomass. Suitable feedstocks from the forest industry include pulp and paper mill residues, sawmill and logging residues, and solid municipal waste. It takes approximately 2 kg of cellulose to produce 1 kg of levulinic acid (US Department of Energy 1998). Obtaining enough raw materials to support the production of levulinic acid from biomass is not a foreseeable concern; Canada currently produces over 75 million tonnes of logging residues annually which, in turn, could produce 19 million tonnes of levulinic acid.

Product Application of Levulinic acid CAS#123-76-2
It can be used as the raw materials of medicine, spices and paint, and used as solvent.
This product has wide applications. Levulinic acid can be used as both a carboxylic acid and can also be used as a ketone for reaction for making various kinds of products through esterification, halogenation, hydrogenation, oxidation dehydrogenation, condensation, etc., including resins, pharmaceuticals, spices, solvents, rubber and plastic additives, lubricants additives, surfactants and so on. In the pharmaceutical industry, its calcium salt (calcium fructose) can be used for intravenous injection. As a nutritional medicine, it helps to boost the formation of bone and maintain the normal excitability of nerves and muscles. It can also used for the production of indomethacin and plant hormones. Levulinic acid manufactured bisphenol acid can be made of water-soluble resin, used in the paper industry to produce filter paper. Levulinic acid is also an intermediate of pesticides and dyes.
Used for biochemical reagents, but also for organic synthesis
It can be used as an important chemical raw material or solvents. It can be used for the manufacturing of medicine (intravenous injection, indomethacin, etc.), resin (bisphenol acid water-soluble resin), spices (spices or tobacco spices), paint, paint, pesticides, and surfactants.
It can be used for biochemical research; manufacturing of esters and drugs. It is also the inhibitor of chlorophyll synthesis.
