Descripción

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.

Aplicaciones
El hidróxido de bario octahidrato se ha utilizado en la técnica de bandas de heterocromatina centromérica y para sintetizar el BaTiO3. Se ha observado que la forma de hidróxido de bario catalizaba la tasa de eliminación β de residuos de fosfoserina. También se utiliza como aditivo de uso general para lubricantes y grasas, fabricación de azúcar, fabricación de jabones, saponificación de grasas y síntesis química de otros compuestos de bario.

Solubilidad
Soluble en agua (72 mg/ml a 20 °C), metanol, etanol (ligeramente) y agua (56 mg/ml a 15 °C). Insoluble en acetona (prácticamente)
