Supplier: Medchemexpress LLC HY14007310MG
endo-BCN-PEG4-PFP ester is a PEG-based bifunctional linker combining a strained alkyne (BCN) for strain-promoted alkyne-azide cycloaddition with a pentafluorophenyl (PFP) activated ester for efficient conjugation to primary amines. Supplied as an oil, it is designed for use in click chemistry, bioconjugation, and linker assembly in targeted degrader synthesis.
- Enables strain-promoted alkyne-azide cycloaddition (SPAAC) without copper.
- PFP ester reacts efficiently with primary amines to form stable amide bonds.
- PEG4 spacer improves solubility and reduces steric hindrance.
- Suitable for bioconjugation and targeted degrader linker construction workflows.
- Stable when stored frozen; follow recommended storage conditions for longevity.
