Oct 4, 2022 · azide: [noun] a compound containing the group N3 combined with an element or radical. Feb 24, 2020 · Abstract. The exceptional reactivity of the azide group makes organic azides a highly versatile family of compounds in chemistry and the material sciences. One of the most prominent reactions employing organic azides is the regioselective copper (I)-catalyzed Huisgen 1,3-dipolar cycloaddition with alkynes yielding 1,2,3-triazoles. Azide is a moderately good leaving group and acyl azides have a special place in amide bond formation. It is probably the least active acylating agent that works adequately at room temperature—reaction times are typically several days at 0 °C (cf. methyl esters are usually too unreactive unless heated to ca. 100 °C).

Azide. Azide is the anion with the formula N 3−. It is the conjugate base of hydrazoic acid. Azide is also a functional group in organic chemistry, RN 3 [1]. N 3− is a linear anion that is isoelectronic with CO 2 and N 2 O. Per valence bond theory, azide can be described by several resonance structures, an important one being N−=N+=N− . Storage temperatures. For many of our antibodies, freezing at -20oC or -80oC in small aliquots is the optimal storage condition. Aliquotting minimizes damage due to freezing and thawing, as well as contamination introduced by pipetting from a single vial multiple times. Aliquots are to be frozen and thawed once, with any remainder kept at 4oC. Exposure to small amounts of sodium azide can result in rapid breathing, restlessness, dizziness, weakness, headache, nausea, vomiting, rapid heart rate, red eyes, clear drainage from the nose, coughing, skin burns, and blisters.

My understanding of why this is valid is that this gives a formal charge of (0) ( 0) for every atom, as opposed to averaging out to that. I suppose the second form makes sense, as it's a lower formal charge on the central atom.
