I. [Product Description]
HS-PEG-Biotin (Thiol-Polyethylene Glycol-Biotin) is a high-performance organic intermediate that combines the high affinity of biotin with the spatial modification properties of the PEG chain. The thiol group (-SH) in its molecule can participate in coupling reactions in a directed manner and is widely used in the synthesis of pharmaceutical intermediates and the construction of catalytic systems. By precisely controlling the molecular weight of PEG (2000-20000), the solubility and molecular recognition efficiency of the product can be optimized.

II. [Product Details]
【Appearance】 Depending on the molecular weight, it appears as a white/off-white solid or a viscous liquid.
【Stability】 Store under refrigeration and avoid repeated freezing and thawing.
【Solvent】 Common organic solvents such as chloroform, dichloromethane, and DMSO.
【Molecular Weight】 (PEG): 2000, 3400, 5000. Other molecular weights can be customized.
