Azide Sources - Diazo Transfer

Explore range of organic azides and azide sources for tailor-made organic azides. 

Azides are a class of chemical compounds containing three nitrogen atoms as a group and represented by (-N3). Azides are very versatile and valuable synthetic intermediates, known for their wide variety of applications and have been employed for the synthesis of a number of important heterocyclic compounds. Sigma-Aldrich offers a wide selection of azide sources, from sodium azide to diphenyl phosphoryl azide to facilitate azide synthesis and the preparation of tailor-made organic azides.
