Ammonium acetate

Ammonium acetate (CAS 631-61-8 ), also known by its food additive designation E264 , is an ammonium salt used across food, pharmaceutical, and analytical chemistry applications.

It functions as a buffering agent, preservative, and pH regulator, and serves as a catalyst precursor in select organic synthesis processes. In food and beverage production, it is approved for use as a preservative.

It acts as an acidity regulator in baked goods, condiments, and meat products. Analytical and biotech laboratories rely on it as a volatile buffer in HPLC mobile phases and LC-MS workflows.

Its low residue profile is critical for instrument compatibility. Pharmaceutical formulators use it to prepare buffered solutions and as a reagent in API synthesis, particularly in reductive amination reactions.

In personal care, it functions as a humectant and pH stabilizer in lotions and topical formulations. The product is supplied as a white crystalline powder or granules for various industrial needs.

Standard grades include food-grade ( FCC , E264-compliant), USP / BP for pharmaceutical use, and high-purity analytical grades meeting HPLC and LC-MS specifications.

Technical grade is available for industrial and catalyst applications. This versatile chemical ensures stability and precision across diverse manufacturing and laboratory environments.
