Diphenylphosphoryl azide (DPPA) is an organic compound. It is widely used in synthesis of other organic compounds. Diphenylphosphoryl azide has been obtained by reaction of the phosphorochloridate with sodium azide.
Lead azide (Pb(N3)2) is an inorganic compound. More so than other azides, Pb(N3)2 is explosive. It is used as a detonators to initiate secondary explosives. In a commercially usable form, it is a white-to-buff powder.
Azide is the anion with the formula N3−. It is the conjugate base of hydrazoic acid. N3− is a linear anion that is isoelectronic with CO2 and N2O. Per valence bond theory, azide can be described by several resonance structures, an important one being N−=N+=N−.
Potassium Azide is the chemical compound having the formula KN3. It is a salt of hydrazoic acid, and crystallizes in a tetragonal structure.
Sodium azide is the inorganic compound with the formula NaN3. This colourless azide salt is the gas-forming component in many car airbag system.
