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.
This Thermo Scientific Chemicals brand product was originally part of the Alfa Aesar product portfolio. Some documentation and label information may refer to the legacy brand. The original Alfa Aesar product / item code or SKU reference has not changed as a part of the brand transition to Thermo Scientific Chemicals.
Applications
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.
Solubility
Soluble in water (72 mg/ml at 20°C), methanol, ethanol (slightly), and water (56 mg/ml at 15°C). Insoluble in acetone (practically)
Notes
Air Sensitive. Store in cool dry place in tightly closed container. With good ventilation. Store away from air and oxidizing agent.
