Zinc Phosphide (CAS 1314-84-7): Properties, Uses, and Safety Information

Zinc phosphide is an inorganic compound used primarily as a rodenticide. It is a dark gray, amorphous or crystalline powder with a characteristic garlic-like odor. The compound is moisture-sensitive and decomposes slowly in water, producing toxic phosphine gas.

**Uses:** - Rodenticide and insecticide - Chemical synthesis - Catalysis - Inorganic chemistry applications

**Safety Information:** - Highly toxic if ingested - Moisture-sensitive - Reacts with water and acids to produce toxic phosphine gas - Flammable when exposed to heat or flame - Incompatible with strong acids and oxidizing agents

Frequently Asked Questions

**Q: How does zinc phosphide work as a rodenticide?**

A: Zinc phosphide reacts with the acidic conditions in the rodent's gut to form phosphine gas, which interferes with cell respiration, leading to the death of the rodent.

**Q: What precautions should be taken when handling zinc phosphide?**

A: Zinc phosphide should be handled with care, avoiding moisture exposure and contact with acids. Proper personal protective equipment should be used, and the compound should be stored in a dry, inert atmosphere.

**Q: Is zinc phosphide approved for agricultural use?**

A: Yes, zinc phosphide is registered as a restricted use pesticide (RUP) in the United States and is approved for use in EU countries for controlling various rodent species in agricultural settings.
