It is used in the production of polyester resins and polyhydric alcohols. It is also used as a mordant for dyes, paint additives, coating additives, plasticizers, processing aids and specific to petroleum production. Further, it is used in dentifrices as a stain remover and to make other chemicals. In addition to this, it is used in rosin esters, drying oils, printing inks and flavoring agent. product description： Fumaric acid can be prepared by fermentation by employing Rhizopus species. Recently, industrial-scale synthesis of fumaric acid from renewable feedstocks and lignocellulosic biomass has been proposed.Fumaric acid has been used as a standard for the quantitative determination of phenolic compounds in nettle samples by HPLC.Fumaric acid may be used in the preparation of L-Lysine-fumaric acid crystals. It may also be employed for the industrial manufacture of synthetic resins and eco-friendly/biodegradable polymers.
