II. [Product Details]
【Appearance】 Depending on different molecular weights, it appears as a white/off-white solid or a viscous liquid.
【Stability】 Long-term stability: Store at 4°C in a sealed and dry environment (avoid moisture absorption and caking). Freeze-thaw sensitivity: ≤3 freeze-thaw cycles (repeated freeze-thawing may cause the breakage of PEG chains and the HPLC purity to decrease by more than 2%).
【Solvents】 Recommended solvents: Chloroform (preferentially dissolves the phospholipid segment), dichloromethane, DMSO and other common organic solvents.
【Molecular Weight】 Standard PEG chain molecular weights: 2000 Da (±3%), 3400 Da (±3%), 5000 Da (±3%), with a batch-to-batch CV < 2%.
Customization range: 1000-20000 Da (end-functional group modification requirements need to be provided).
【Storage Conditions】 Original packaging: Store at a low temperature below 4°C, sealed in a double-layer aluminum foil bag (humidity < 10% RH).
After opening:
▶ For solids: Sub-package into 1 mL brown glass bottles and seal with nitrogen.
▶ For liquids: Avoid contact with water and oxygen. It is recommended to add 0.02% BHT antioxidant.
▪ Notes: ▶ To ensure product stability, please open the package for use only after constant-temperature drying!
