Medchemexpress LLC Biotin-C5-Azide (DecarboxyBiotin-N3) | 1260586-88-6 | C10H17N5OS | 1 ML
Biotin-C5-Azide (DecarboxyBiotin-N3) is a biotin reagent used to prepare biotinylated conjugates. It functions as a click chemistry reagent, containing an Azide group that allows it to participate in copper-catalyzed azide-alkyne cycloaddition (CuAAc) reactions with alkyne-containing molecules. Additionally, it can undergo strain-promoted alkyne-azide cycloaddition (SPAAC) reactions with molecules containing DBCO or BCN groups.
