Overview

Barium(2+);dihydroxide;octahydrate (CAS 12230-71-6) is an inorganic barium compound with high water solubility and alkaline properties. This hydrated barium hydroxide represents a significant industrial chemical characterized by its crystalline octahydrate form, containing eight molecules of water per formula unit. With the molecular formula BaH18O10 and a molar mass of 315.46 g/mol, this compound exhibits strong basic properties in aqueous solutions, making it valuable for various chemical processes requiring controlled alkalinity. The compound demonstrates excellent solubility in water, releasing hydroxide ions that create highly alkaline conditions. Its crystalline structure incorporates water molecules that contribute to its stability under ambient conditions while allowing for controlled release during chemical reactions. The material requires careful handling due to its classification under ADR Class 8, indicating corrosive properties that necessitate appropriate safety protocols during storage and use. Industrial applications include its role as a strong base in organic synthesis reactions, particularly in processes where controlled pH adjustment is critical. The compound serves effectively in wastewater treatment applications where neutralization of acidic industrial effluents is required. Additionally, it functions as a precursor in the manufacture of other barium compounds and finds application in certain analytical chemistry procedures. Unlike reactive acyl compounds such as 4-methoxybenzoyl chloride or benzene-1,4-dicarbonyl chloride, this barium hydroxide provides stable alkaline conditions without the moisture sensitivity typical of chloride-based reagents. The octahydrate form ensures consistent performance and simplified handling compared to anhydrous variants, making it particularly suitable for applications requiring precise stoichiometric control. OYSI maintains reliable supplies of high-quality barium(2+);dihydroxide;octahydrate to support diverse industrial applications across European markets.
