Ammonium fumarate

Ammonium fumarate (CAS 14548-85-7 ), also known as diammonium fumarate and approved as E368 , is the ammonium salt of fumaric acid used commercially as a pH buffer and acidulant. It provides controlled acidity adjustment and mild preservative action across food, pharmaceutical, and agricultural formulations. In food manufacturing, it functions as a buffering agent in baked goods and beverages. Stable pH control directly affects shelf life and product consistency in processed foods. Pharmaceutical formulators use it as an excipient to regulate pH in oral solid dosage forms and as a counterion in salt formation. In animal feed applications, it acts as an acidifier to manage gastrointestinal pH, supporting feed hygiene and palatability. Agricultural formulations incorporate it as a buffering component in liquid fertilizers. It is also used in crop protection products to stabilize solution pH during mixing and application. Ammonium fumarate is supplied as a white crystalline powder or granules for various industrial uses. Food-grade material conforming to E368 specifications is the most commonly traded form. Technical-grade is available for agricultural and industrial applications where high purity is not the primary requirement. Pharmaceutical-grade supply is sourced to meet compendial purity requirements where excipient documentation is required. This ensures the material meets the necessary safety standards for medical applications. Contact us for supply of Ammonium fumarate Request Quote
