Propargyl-dPEG®1-NHS ester, product number QBD-10511, is a crosslinking click chemistry reagent. The alkynyl end of the molecule reacts with azides via copper(I) or ruthenium catalysis to form 1,3- or 1,5-dipolar cycloaddition products, respectively. The NHS ester end of the molecule reacts with primary and secondary amines to form stable amide bonds.
| Unit Size | 100 mg, 1000 mg |
|---|---|
| Molecular Weight | 225.20; single compound |
| Chemical formula | C₁₀H₁₁NO₅ |
| CAS | 1174157-65-3 |
| Purity | > 98% |
| Spacers | dPEG® Spacer is 7 atoms and 7.2 Å |
| Shipping | Ambient |
| Typical solubility properties (for additional information contact Customer Support) | Methylene chloride, DMAC, DMSO |
| Storage and handling | -20°C; Always let come to room temperature before opening; be careful to limit exposure to moisture and restore under an inert atmosphere; stock solutions can be prepared with dry solvent and kept for several days (freeze when not in use). dPEG® pegylation compounds are generally hygroscopic and should be treated as such. This will be less noticeable with liquids, but the solids will become tacky and difficult to manipulate, if care is not taken to minimize air exposure. |
