Ha másként nem jelöljük, az adatok az anyag standardállapotára (100kPa) és 25°C-os hőmérsékletre vonatkoznak. Azides decompose with nitrite compounds such as sodium nitrite when acidified. This is a method of destroying residual azides, prior to disposal. [6] In the process, nitrogen, nitrogen oxides, and hydroxides are formed: Mandler, Michael D.; Degnan, Andrew P.; Zhang, Shasha; Aulakh, Darpandeep; Georges, Ketleine; Sandhu, Bhupinder; Sarjeant, Amy; Zhu, Yeheng; Traeger, Sarah C.; Cheng, Peter T.; Ellsworth, Bruce A.; Regueiro-Ren, Alicia (28 January 2022).

PMID 34714083. S2CID 240154010.Many inorganic covalent azides (e.g., chlorine, bromine, and iodine azides) have been described. [5]

The azide anion behaves as a nucleophile; it undergoes nucleophilic substitution for both aliphatic and aromatic systems. It reacts with epoxides, causing a ring-opening; it undergoes Michael-like conjugate addition to 1,4-unsaturated carbonyl compounds. [1]The scope of this reaction has been extended to reactions of carbonyls with alkyl azides R-N 3. This extension was first reported by J.H. Boyer in 1955 [9] (hence the name Boyer reaction), for example, the reaction of m-nitrobenzaldehyde with β-azido-ethanol: A nátrium-azid egy kémiai vegyület, a hidrogén-azid nátriumsójának tekinthető. Képlete NaN 3. Színtelen por, vízben jól oldódik. Légzsákokban, és ólom-azid előállítására használják. I. C. Tornieporth-Oetting & T. M. Klapötke (1995). "Covalent Inorganic Azides".
