Overview
Barium acetate (CAS 543-80-6 ), also known as barium diacetate, is an inorganic barium salt used primarily as a catalyst precursor and chemical intermediate in industrial synthesis.
It delivers controlled barium ion release in processes requiring precise metal salt activity, making it a functional choice for catalyst preparation and specialty chemical manufacturing.
In catalyst production, barium acetate serves as a precursor for barium-containing catalysts used in organic synthesis and petroleum refining processes for various industrial applications.
Pharmaceutical manufacturers use it as a reagent and intermediate where controlled barium content is required in API synthesis workflows to ensure consistent chemical reactions and outcomes.
In laboratory and analytical settings, it functions as a pH buffer and precipitation agent for sulfate detection and gravimetric analysis, providing reliable results for researchers.
Specialty chemical formulators also draw on it for the preparation of barium-based compounds where acetate acts as a reactive leaving group during thermal decomposition or calcination.
Barium acetate is supplied as a white crystalline powder or granular solid. It is available in technical and reagent grades, with purity specifications typically ranging from 98% to 99%+.
Quality standards are maintained throughout production to meet specific end-use requirements. Packaging options generally range from laboratory-scale quantities to bulk industrial supply.
