Br-PEG2-N3 (Bromo-PEG2-azide) is a heterobifunctional crosslinking reagent featuring both a bromide and an azide group. The azide group allows for click chemistry reactions with alkyne, BCN, or DBCO groups, while the bromide serves as an effective leaving group for nucleophilic substitution.

This PEG2-based linker is widely used in the synthesis of antibody-drug conjugates (ADCs) as a stable, non-degradable linker, and also as a PROTAC linker in targeted protein degradation. Its versatile reactivity and solubility make it a valuable tool in bioconjugation and drug discovery applications.

Biopharma PEG offers a wide range of PEG linkers on both lab and commercial scales. Email at sales@biochempeg.com and start using a superior product for your next product R&D project.
