FAQ

What is Dioxomanganese (CAS: 1313-13-9)?

Dioxomanganese (CAS: 1313-13-9) refers to manganese dioxide (MnO2), a chemical compound composed of manganese and oxygen. It is a black, inorganic solid with strong oxidizing properties, commonly used in various industrial and scientific applications. Manganese dioxide has a high melting point and is stable under normal conditions, though it may react with reducing agents.

What are the main uses of Dioxomanganese (CAS: 1313-13-9)?

Dioxomanganese (CAS: 1313-13-9), or manganese dioxide, is widely used in batteries (e.g., alkaline and zinc-manganese cells), as a catalyst in chemical reactions, in pigments and ceramics, and for water treatment. It also serves as an oxidizing agent in pharmaceutical synthesis and industrial processes, and is studied in research for its electrochemical properties.

Is Dioxomanganese (CAS: 1313-13-9) safe?

Dioxomanganese (CAS: 1313-13-9), manganese dioxide, is generally considered safe when handled properly. However, inhalation or ingestion can cause toxicity, so protective measures like gloves, goggles, and ventilation are recommended. Safety standards emphasize avoiding prolonged exposure and ensuring compliance with OSHA and EPA guidelines for industrial use.

How should Dioxomanganese (CAS: 1313-13-9) be stored?

Dioxomanganese (CAS: 1313-13-9) should be stored in a cool, dry, and well-ventilated area, away from moisture and incompatible substances. It is best kept in airtight, dark-colored containers to prevent light exposure. Ensure storage in a place with stable temperature and humidity levels to maintain its chemical integrity and safety.
