Thiol-PEG4-alcohol is a chemical reagent with a unique structure and is widely used in the field of biochemical research. This product features a precisely designed structure, linked by thiol groups and polyethylene glycol (PEG), with an alcohol hydroxyl group at the end. Its structural formula is XX-PEG4-OH, which is highly professional and academic. The production process is rigorous to ensure the stability and reliability of product quality. Under strictly controlled reaction conditions, thiol groups and PEG chains are synthesized through specific reactions, and then the final product is obtained after purification and detection. Thiol-PEG4-alcohol is often used in scenarios such as the modification of biomolecules and the functionalization of material surfaces. Its high reactivity and good biocompatibility make it occupy an important position in biochemical research. In addition, it is also widely applied in fields such as drug research and development and materials science.
