Azide Phosphoramidite in Direct Synthesis of Azide-Modified Oligonucleotides
Organic Letters, 2014Azide and phosphoramidite functions were found to be compatible within one molecule and stable for months in solution kept frozen at -20 °C. An azide-carrying phosphoramidite was used for direct introduction of multiple azide modifications into synthetic oligonucleotides.

Solubility of Sodium Azide and Alpha-Lead Azide.
Journal of Chemical & Engineering Data, 1966The solubility of sodium azide was determined in water and in 40, 60, 80, and 95.5% ethanol-water mixtures, respectively. The solubilities were first determined by a synthetic method (9) which involved the preparation of a solution of known composition, the saturation point of which was determined by varying the temperature.

Ionic liquid azides from azidoethyl, alkyl, and alkenyl substituted derivatives of 1,2,4- and 1,2,3-amino-triazoles were prepared and examined for the first time to investigate their structural and physical properties. All reported salts possess melting points below 100 degrees C.

AbstractAzide compounds are widely used and especially, polymers bearing pendant azide groups are highly desired in numerous fields. However, harsh reaction conditions are always mandatory to achieve full azidation, causing severe side reactions and degradation of the polymers.

Hydrazine hydrate (1.67 ml = 1.72 g, 34 mmol) is added to a solution of N-benzyloxycarbonyl-S-benzyl-l-cysteinyl-l-seryl-l-histidine methyl ester [1, 2] (5.84 g, 10 mmol) in methanol [3] (50 ml) and the reaction mixture is kept at room temperature for 3 days [4].

Starch is an inexpensive commodity that has been used for non-food purposes for many years. Some of these uses include cross-linked starches that are synthesized with a variety of multifunctional reagents. One unexplored possibility is the use of azides for cross-linking.

AbstractPure, solvent‐free Zn(N3)2 was prepared by reaction of diethyl zinc and hydrazoic acid in aprotic solvents. The single‐crystal structure determination, along with the comprehensive characterization of α‐Zn(N3)2 and two metastable polymorphs, could be achieved for the first time.

Structure of azide methemoglobin
Journal of Molecular Biology, 1979Abstract We have compared the structures of horse azide methemoglobin and methemoglobin (MetHb) at 2.8 A resolution by X-ray difference Fourier analysis. Of four low-spin liganded Hb derivatives (nitric oxide Hb, carbon monoxide Hb, cyanide MetHb, and azide MetHb), azide MetHb is closest in structure to MetHb.
