Medchemexpress LLC M-PEG3-aldehyde (stabilized with BHT) | 356066-46-1 | MFCD26910955 | 98.0% | 176.21 g/mol | C8H16O4 | 5MG
m-PEG3-aldehyde (stabilized with BHT) is a methoxy-terminated polyethylene glycol linker containing three ethylene glycol units and a terminal aldehyde. Provided for research use, it serves as a short, aldehyde-functionalized spacer for small-molecule conjugation and PROTAC synthesis; the BHT stabilizer helps reduce oxidation during storage and handling.
- Terminal aldehyde enables oxime formation and reductive amination conjugation chemistries.
- Short PEG3 spacer provides flexibility and improves solubility without large steric bulk.
- Stabilized with BHT to limit oxidative degradation during storage.
- High purity (98.0%) suitable for synthetic and medicinal chemistry applications.
- Available in small milligram pack sizes for bench-scale workflows.
