Medchemexpress LLC Propargyl-PEG1-NHS ester | 1174157-65-3 | 99.7% | 225.20 g/mol | C10H11NO5 | 250 MG
A non-cleavable one-unit polyethylene glycol (PEG) linker supplied as an NHS ester with a terminal propargyl (alkyne) group. Designed for click chemistry (CuAAC) and antibody-agent conjugation, it is provided as a colorless to light-yellow solid-liquid mixture with high purity and recommended cold storage.
- One-unit PEG linker for minimal spacer length.
- Terminal alkyne enables copper-catalyzed azide-alkyne cycloaddition (CuAAC).
- NHS ester allows efficient coupling to primary amines.
- High purity suitable for conjugation chemistry.
- Cold storage recommended for long-term stability.
Medchemexpress LLC Propargyl-PEG1-NH2 100mg | 122116-12-5 | 99.13 g/mol | C5H9NO | 100 MG
Propargyl-PEG1-NH2 is a short polyethylene glycol linker bearing a terminal propargyl (alkyne) group and a primary amine. It is used as a bifunctional coupling handle in medicinal chemistry and bioconjugation workflows, and is compatible with click chemistry for assembling conjugates such as PROTACs.
- Short PEG1 linker with terminal alkyne and primary amine.
- Facilitates copper-catalyzed azide-alkyne cycloaddition (click) conjugations.
- High purity (98.8%) suitable for research and synthetic applications.
- Available in small research pack sizes for rapid screening and synthesis.
- Store at 4°C and protect from light; aliquot prepared solutions to avoid repeated freeze-thaw cycles.
