Used as a catalyst in organic synthesis, particularly in esterification and condensation reactions. Employed in the production of barium-based pigments and dyes for ceramics and glass, where it helps achieve specific color and clarity. Applied in the leather tanning industry to improve dye uptake and color fastness. Also utilized in the preparation of other barium salts and in some flame retardant formulations due to its thermal stability and ability to release acetate groups upon heating.
