Amino-PEG10-OH is a 10-unit polyethylene glycol (PEG) linker bearing a terminal primary amine, used as a non-cleavable spacer in bioconjugation. It is commonly employed in the synthesis of antibody-drug conjugates (ADCs) and proteolysis targeting chimeras (PROTACs) to provide hydrophilic spacing and a reactive site for payload attachment. The material is typically supplied as a white to off-white solid (CAS 129449-09-8) with a molecular weight of 457.56 g/mol.

• Non-cleavable 10-unit PEG spacer suitable for ADC and PROTAC chemistry.
• Terminal primary amine enables straightforward conjugation to activated esters and acids.
• Hydrophilic spacer improves solubility and reduces steric hindrance between conjugated components.
• High purity suitable for research applications.
• Available in laboratory quantities such as 250 mg for small-scale synthesis.
