FAQ

What is stannous oxygen(-2) anion (CAS: 21651-19-4)?

Stannous oxygen(-2) anion (CAS: 21651-19-4) refers to the oxygen ion with a -2 charge in tin compounds, commonly found in tin(II) oxide (SnO). It is a basic oxide, typically appearing as a white solid, and exhibits reducing properties in chemical reactions. This anion plays a key role in various industrial and scientific applications due to its reactivity and stability in specific environments.

What are the main uses of stannous oxygen(-2) anion (CAS: 21651-19-4)?

Stannous oxygen(-2) anion (CAS: 21651-19-4) is primarily used in pharmaceuticals as a catalyst for organic reactions, in the production of tin-based compounds like stannous chloride, and in glass manufacturing to enhance thermal resistance. It also finds applications in research for material synthesis and in industrial coatings for corrosion protection, leveraging its chemical reactivity and oxide properties.

Is stannous oxygen(-2) anion (CAS: 21651-19-4) safe?

Stannous oxygen(-2) anion (CAS: 21651-19-4) is generally considered low in toxicity compared to other tin oxides, but handling precautions are still necessary. Inhalation of its dust may irritate the respiratory system, so protective gear like gloves and masks is recommended. Safety standards emphasize avoiding contact with skin and eyes, and proper ventilation in workspaces to ensure safe usage in chemical processes.

How should stannous oxygen(-2) anion (CAS: 21651-19-4) be stored?

Stannous oxygen(-2) anion (CAS: 21651-19-4) should be stored in a cool, dry place (ideally below 25°C) to maintain stability. It is sensitive to moisture, so airtight, moisture-proof containers are essential. Protection from light and storage away from strong oxidizing agents are recommended to prevent degradation. Always follow manufacturer guidelines for safe handling and storage conditions.
