Fmoc-L-Lys (4-N3-Z) -OH

Fmoc-L-Lys (4-N3-Z) -OH is a click chemistry reagent containing an azide group. Fmoc-L-Lys (4-N3-Z) -OH acts as Lysine building-block for SPPS containing an Azide moiety as a bioorthogonal ligation handle, an infrared probe and a photo-affinity reagent. It can be decaged by trans-cyclooctenols via a strain-promoted 1,3-dipolar cycloaddition[1][2]. Fmoc-L-Lys (4-N3-Z) -OH is a click chemistry reagent, it contains an Azide group and can undergo copper-catalyzed azide-alkyne cycloaddition reaction (CuAAc) with molecules containing Alkyne groups. It can also undergo strain-promoted alkyne-azide cycloaddition (SPAAC) reactions with molecules containing DBCO or BCN groups.
