Description
Barium acetate (CAS 543-80-6; EC 208-849-0; also listed as barium diacetate and acetic acid barium salt) is an inorganic barium salt of acetic acid with the formula C2H4O2·1/2Ba. It carries no assigned E-code and is commercially available in ACS and 99.999% purity designations.
In catalytic applications, barium acetate acts as a promoter or co-catalyst in organic synthesis reactions, including esterification and oxidation processes, where the barium ion coordinates with reactive intermediates to improve selectivity. It also functions as a pH buffer in pharmaceutical and personal care formulations, stabilising acidic environments through controlled acetate ion release.
Barium acetate is supplied as a white crystalline powder in ACS-grade and high-purity 99.999% grades, with procurement subject to REACH registration requirements within the EU. Buyers should verify compliance documentation, as the compound falls under HS code 29152900 and requires appropriate handling classifications for transport and storage.
