Hydrazoic acid (HN3) and its deprotonated form azide ion (N3−) (AHA) are toxic because they inhibit the cytochrome c oxidase complex IV (CoX IV) embedded in the inner mitochondrial membrane that forms part of the enzyme complexes involved in cellular respiration. Critical to its toxicity is the inhibition of CoX IV in the central nervous system and cardiovascular system. Hydrazoic acid is an ...Except where otherwise noted, data are given for materials in their standard state (at 25 °C [77 °F], 100 kPa). ?)
