Product Description
Barium acetate (CAS 543-80-6, Ba(CH₃COO)₂) is a white crystalline inorganic salt, highly soluble in water and slightly soluble in ethanol. It is a standard water-soluble barium source used as a mordant, analytical reagent, catalyst and precursor for other barium compounds and barium-containing materials.
Key features:
White crystalline powder, free-flowing and easy to dissolve.
High water solubility, convenient for aqueous formulation.
Decomposes on heating above ~450 °C to barium carbonate/oxide.
Reliable source of Ba²⁺ for precipitation and catalyst preparation.
Tight control of chloride, sulfate and heavy-metal impurities.
Available in reagent and industrial grades.

Product Application
Barium acetate is a specialty barium salt mainly used in analytical chemistry, textile dyeing, organic catalysis and the preparation of other barium compounds.
In analytical chemistry, it is used for the gravimetric determination of sulfate and chromate, for calcium analysis, and as a standard reagent in qualitative and quantitative test methods.
In textiles and leather, it acts as a mordant and fixing agent that improves dye uptake and wash fastness of direct and acid dyes on fibers and leather.
In organic synthesis and catalysis, it serves as a catalyst or catalyst precursor for selected condensation, oxidation and esterification reactions, and as a Ba²⁺ source for the sol-gel preparation of barium titanate (BaTiO₃) and other electronic ceramics.
In industry, it is an intermediate for manufacturing other barium salts, barium-containing paints and anti-corrosion pigments, and is used in specialty glass and brick formulations.
