Following is the molecular structure of Aluminium phosphide (CAS NO.8005-48-9):

 

 Aluminium phosphide (CAS NO.8005-48-9) is used as insecticide for the fumigation, both fumigation unprocessed food grains, refined grains, but also seeds of grain fumigation, and various storage devices. It is also used in other enclosed spaces, holes and other rodent control and trunk eliminate alternatus. Fumigation of grain when the dosage is 10 ~ 30 g / t grain; warehouse fumigation when the dosage is usually 1 to 4 / m³.

Reactivity Profile: Aluminum phosphide (CAS NO.8005-48-9) is a reducing agent. Contact with mineral acids causes explosive evolution of toxic phosphine [Wang, C. C. et al., J. Inorg. Nucl. Chem., 1963, 25, p. 327]. Heating produces highly toxic fumes of phosphorus oxides. Can react vigorously upon contact with oxidizing agents. [Sax, 9th ed., p. 119].

Aluminium phosphide (CAS NO.8005-48-9) is the chemical compound with the empirical formula AlP. This colourless solid is generally sold as a grey-green-yellow powder due to the presence of impurities arising from hydrolysis and oxidation. This material is a wide band gap semiconductor and is used as a fumigant.
