Zinc phosphide
Zinc phosphide (CAS: 1314-84-7, Formula: Zn₃P₂) is a grey to black crystalline solid with a molecular weight of 258.12 g/mol. It is a binary compound of zinc and phosphorus. This chemical is primarily recognised for its application as a rodenticide and insecticide. It also finds use in certain chemical synthesis processes and as a component in inorganic chemistry research, owing to its unique chemical properties. Tech Serve Solutions supplies Zinc phosphide for industrial and research purposes.

Rodenticide and Insecticide
Zinc phosphide is widely utilised as a highly effective rodenticide for controlling populations of rats, mice, and other rodents. Its mode of action involves the release of phosphine gas upon contact with stomach acid, which is toxic to pests.
Chemical Synthesis
This compound serves as a precursor or reagent in various chemical synthesis pathways. It can be employed in the preparation of organophosphorus compounds and other complex inorganic structures.
Inorganic Chemistry
Zinc phosphide is a valuable material in inorganic chemistry research, contributing to studies on binary metal phosphides and their properties. Its electrochemical and material science applications are areas of ongoing investigation.
