Barium chloride dihydrate is an inorganic salt composed of barium, chlorine, and water of crystallization, widely used in chemical analysis, metallurgy, and as a precursor in the production of barium compounds, pigments, and heat treatment baths. Industrial buyers also use it in glass manufacturing, color lake production, as a mordant in textile dyeing, in aluminum refining, and in leather tanning and finishing. It appears as a white crystalline solid with high solubility in water. This chemical has a CAS number of 10326-27-9, a molecular formula of BaCl₂·2H₂O, and a molecular weight of 244.26 g/mol. It must be stored at ambient conditions, handled with caution (Signal Word: Danger), and kept away from moisture-sensitive materials. Molekula supplies barium chloride dihydrate from research to bulk quantities with full documentation and ISO 9001:2015 traceability.
