Description

Fumaric Acid is a key industrial dicarboxylic acid and a vital intermediate in organic synthesis. Its primary value lies in its versatility as an acidulant, flavor enhancer, and chemical building block, offering a cost-effective and efficient alternative to other food acids. This compound is essential for manufacturers in the food and beverage, pharmaceutical, and polymer resin industries. We supply high-purity Fumaric Acid CAS NO 6315-18-0 to meet the stringent demands of global B2B customers.

Application

• Food & Beverage Acidulant: Used as a tart, long-lasting acidifier in beverages, gelatin desserts, and baking powders, often as a substitute for citric or tartaric acid.
• Animal Feed Preservative & Acidifier: Enhances feed palatability, inhibits microbial growth, and improves nutrient absorption in livestock and poultry feed.
• Unsaturated Polyester Resins (UPR): A critical raw material in the production of UPRs, which are used in fiberglass-reinforced plastics for marine, automotive, and construction applications.
• Pharmaceutical Intermediate: Serves as a starting material or intermediate in the synthesis of various active pharmaceutical ingredients (APIs).
• Paper Sizing Agent: Improves the water resistance and strength properties of paper and paperboard products.
• Industrial Chemical Synthesis: A precursor for the production of L-aspartic acid, malic acid, and other fine chemicals.
