Organic azide
open-in-new
<p>An organic azide is an <a href="/facts/Organic_compound/gqCNaN45">organic compound</a> that contains an azide (–N3) <a href="/facts/Functional_group/GXkSPsjM">functional group</a>. Because of the hazards associated with their use, few azides are used commercially although they exhibit interesting reactivity for researchers. Low <a href="/facts/Molecular_mass/FWueGMed">molecular weight</a> azides are considered especially hazardous and are avoided. In the research laboratory, azides are precursors to <a href="/facts/Amine/JvfYJfP6">amines</a>. They are also popular for their participation in the "<a href="/facts/Click_reaction/DzX03jLU">click reaction</a>" between an azide and an alkyne and in <a href="/facts/Staudinger_ligation/s63Hyq9D">Staudinger ligation</a>. These two reactions are generally quite reliable, lending themselves to <a href="/facts/Combinatorial_chemistry/WW2SSJnq">combinatorial chemistry</a>. </p>
