CAS 1304-28-5 — Óxido de bario

Barium oxide (BaO) is a highly reactive alkaline earth metal oxide used in ceramics, glass manufacturing, and as a drying agent for organic liquids. It serves as a precursor in barium compound synthesis and functions as a strong desiccant in laboratory settings. This white to yellowish powder has a CAS number of 1304-28-5, a molecular weight of 153.33 g/mol, and requires careful handling due to its corrosive and hygroscopic properties. It must be stored in a tightly sealed container under ambient conditions, away from moisture and carbon dioxide. The substance carries a **Danger** signal word, indicating severe hazards upon exposure. Molekula supplies barium oxide from research to bulk quantities with full documentation and ISO 9001:2015 traceability.
