Alkyne-PEG-Tosyl (often denoted as PEG1-PEGn) is a functionalized polyethylene glycol reagent featuring terminal alkyne and tosyl groups. It serves as a critical intermediate in bioconjugation and click chemistry synthesis. The general molecular formula varies by chain length, typically CnH2n+2OxS, with specific CAS numbers assigned per PEG spacer size.
Store under inert atmosphere at -20°C to prevent hydrolysis. Handle with appropriate PPE due to potential irritancy; avoid contact with skin and eyes. Not intended for direct clinical use without further purification and formulation.
