Sodium azide

Transform your bioconjugation and click chemistry projects with sodium azide (CAS No.: 26628-22-8, CAT No.: SRCS-005). This premier azide source enables copper-catalyzed azide-alkyne cycloaddition (CuAAC) for 1,2,3-triazole formation, metabolic labeling of biomolecules, and rapid library synthesis in drug discovery and chemical biology.

[1][2][3][4]

With a molecular formula of NaN₃ and a molecular weight of 65.01 g/mol, sodium azide appears as a white crystalline powder highly soluble in water (420 g/L at 20?C). Its exceptional solubility and reactivity make it indispensable for azide introduction in carbohydrates, peptides, proteins, and small molecule conjugates.
