Barium hydroxide octahydrate has been used in the centromeric heterochromatin banding technnique and to synthesize BaTiO3. The form Barium hydroxide was reported to catalyze the rate of β elimination of phosphoserine residues. It is also used as a general purpose additive for lubricants and greases, sugar fabrication, manufacturing soaps, fat saponification and chemical synthesis of other barium compounds.

Preferred base for the Horner-Wadsworth-Emmons reaction with sensitive aldehydes, such as in formation of complex (E)-enones in natural product synthesis: Synlett, 774 (1993).
Suzuki coupling of 4-iodopyridines with arylboronic acids is promoted by this base which has advantages for sterically hindered substrates: J. Organomet. Chem., 517, 25 (1996).
