HO-PEG3-(CH2)6-Cl is a hydroxy-terminated PEG3 linker bearing a six-carbon chlorinated alkyl chain, used as a building block in PROTAC and bioconjugation chemistry. It serves as a flexible, hydrophilic spacer for attaching ligands, tags, or warheads during linker assembly and small-scale synthesis.
- Polyethylene glycol (PEG3) spacer with terminal hydroxy and six-carbon chloride.
- Designed for PROTAC linker assembly and bioconjugation.
- Flexible and hydrophilic to improve solubility and spacing between functional groups.
- Supplied in research-scale packs suitable for method development and small-scale synthesis.
- Molecular formula C12H25ClO4; molecular weight 268.78 g/mol.
- CAS number 1355955-95-1; supplier-reported purity typically 95%.
