I. [Product Description]
Tosyl-PEG-serine (Tosyl-polyethylene glycol-serine) is a multifunctional organic intermediate widely used in the synthesis of pharmaceutical intermediates and bioconjugation reactions. The tosyl group (Tosyl) in its molecule serves as a highly efficient activating group, which can precisely control the reaction sites. Combined with the excellent water solubility and biocompatibility of the PEG chain, it significantly enhances the stability and application potential of the product.

II. [Product Details]
【Appearance】 Depending on different molecular weights, it appears as a white/off-white solid or a viscous liquid.
【Stability】 Store in a refrigerator and avoid repeated freeze-thaw cycles.
【Solvent】 Common organic solvents such as chloroform, dichloromethane, and DMSO.
【Molecular Weight】 (PEG): 2000, 3400, 5000. Other molecular weights can be customized.
【Storage Conditions】 Store in a sealed, dry place at a low temperature below 4°C.
▪ Note: ▶ To ensure product stability, please open the package for use only after constant temperature drying!

III. [Application Areas]
1. Surface functional modification of polymer materials (through directional coupling of the Tosyl group)
2. Biomolecule labeling and probe construction (using the PEG chain to reduce non-specific adsorption)
3. Crosslinking agent for nanodrug carriers (optimizing the stability of the drug delivery system)
4. Site-specific modification of proteins/peptides (precisely controlling the reaction sites)
5. Support for transition metal catalysts in organic synthesis
