Ammonium formate

Ammonium formate (CAS 540-69-2, EC 208-753-9, formula CH2O2.H3N) is an ammonium salt of formic acid, also referenced as ammonium formiate or formate d'ammonium. It carries no assigned E-code and is commercially supplied as a colourless crystalline solid under the HS code 29151200.

In pharmaceutical manufacturing, ammonium formate functions as a volatile buffer in HPLC mobile phases, decomposing cleanly upon evaporation without leaving residue on analytical columns. In food and personal care formulations, it acts as an antimicrobial agent and pH regulator, controlling microbial growth by maintaining acidic buffer equilibria at the target pH range.

Ammonium formate is available in technical, food-grade, and Ph.Eur.-compliant grades, with REACH registration applicable for EU supply chains. FCC-grade material meets food additive purity specifications for relevant applications. Standard packaging includes 25 kg bags and intermediate bulk containers, with documentation available to support regulatory submissions.
