Description

Disodium Oxide (CAS NO 1313-59-3) is a powerful inorganic base and a key reagent in various industrial chemical synthesis processes. Its strong alkalinity makes it an essential component for neutralizing acids, catalyzing reactions, and serving as a precursor for other sodium compounds. This high-purity chemical is critical for manufacturers and R&D facilities in the pharmaceutical, fine chemical, and advanced materials sectors seeking reliable, consistent performance in their formulations.

Application

• Chemical Synthesis: Acts as a strong base catalyst in organic synthesis and as a precursor for producing other sodium salts and specialty chemicals.
• Pharmaceutical Intermediate: Used in the synthesis of active pharmaceutical ingredients (APIs) where precise alkalinity control is required.
• Glass & Ceramics Manufacturing: Serves as a fluxing agent to lower the melting point and modify the properties of glass and ceramic batches.
• Metallurgy: Employed in refining processes and as a component in certain fluxes for metal treatment.
• Laboratory Reagent: Utilized as a high-purity analytical reagent and a desiccant for organic solvents in research and quality control laboratories.
• Water Treatment: Functions as a powerful alkaline agent for pH adjustment and neutralization in specific industrial effluent treatment processes.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). This material is hygroscopic (moisture-sensitive) and must be kept under an inert atmosphere or in airtight packaging to prevent reaction with atmospheric moisture and carbon dioxide. Isolate from strong acids and incompatible materials.
