N3-PEG4-C2-NHS ester is a non-cleavable 4-unit polyethylene glycol (PEG) linker containing an azide group and an N-hydroxysuccinimide (NHS) ester for amine coupling; it is used for bioconjugation and click chemistry applications such as antibody-drug conjugate synthesis.
- Azide functional group enables copper-catalyzed azide-alkyne cycloaddition (CuAAC) and strain-promoted alkyne-azide cycloaddition (SPAAC).
- NHS ester reacts with primary amines to form stable amide bonds for labeling.
- Four-unit PEG spacer increases solubility and reduces steric hindrance.
- High purity suitable for research-grade bioconjugation workflows.
- Stable when stored under recommended low-temperature conditions to preserve reactivity.
