Medchemexpress LLC Propargyl-PEG4-CH2CH2-Boc | 1245823-50-0 | 360.44 g·mol⁻¹ | C18H32O7 | 100 MG
Propargyl-PEG4-CH2CH2-Boc is a PEG-based linker bearing a terminal propargyl (alkyne) group and a Boc-protected amine. It is used as a non-cleavable ADC linker, a PROTAC linker, and as a reagent for click chemistry (copper-catalyzed azide-alkyne cycloaddition).
- Contains a terminal alkyne suitable for copper-catalyzed azide-alkyne cycloaddition.
- Boc-protected amine enables orthogonal deprotection strategies.
- Applicable as a non-cleavable ADC linker or a PROTAC linker in conjugation workflows.
- Molecular weight 360.44 g·mol⁻¹; CAS 1245823-50-0.
- Store pure material at -20°C for long-term stability; in solvent store at -80°C for best stability.
