Description

Fumaric Acid CAS NO 110-17-8 is a white, crystalline organic acid with a fruity taste, widely recognized for its safety and versatility as a food additive and industrial intermediate. Its primary value lies in its strong acidity, low cost, and non-toxic nature, making it a preferred acidulant and pH adjuster over other acids in many applications. This compound is essential for manufacturers in the food and beverage, pharmaceutical, and polymer resin industries seeking a reliable and effective multifunctional ingredient.

Application

• Food & Beverage Acidulant: Used in beverages, gelatin desserts, and baking powders for tartness and as a leavening agent.
• Animal Feed Preservative & Acidifier: Enhances feed hygiene and improves nutrient absorption in livestock and aquaculture.
• Unsaturated Polyester Resin (UPR) Production: A key raw material in the synthesis of UPRs for fiberglass-reinforced plastics.
• Pharmaceutical Intermediate: Serves as a starting material for the synthesis of various active pharmaceutical ingredients (APIs).
• Tartaric Acid Synthesis: A primary industrial precursor in the manufacturing of L-(+)-Tartaric acid.
• Paper Sizing Agent: Improves the water resistance and strength properties of paper products.
• Metal Cleaning & Surface Treatment: Acts as a chelating agent and pH regulator in industrial cleaning formulations.
