Boc-NH-PEG1-CH2CH2COOH is a Boc-protected, single-unit polyethylene glycol (PEG1) linker bearing a terminal carboxylic acid. It is intended for use in the synthesis of antibody-drug conjugates (ADCs) and proteolysis-targeting chimeras (PROTACs), providing a hydrophilic spacer and a protected amine for orthogonal chemistry. The material is supplied as a white to off-white solid with specified molecular weight and purity appropriate for research and linker construction.
- Cleavable PEG1 spacer increases solubility and reduces steric hindrance.
- Boc-protected amine enables orthogonal deprotection and coupling strategies.
- Terminal carboxylic acid allows straightforward amide bond formation.
- Compact linker length helps preserve biological activity of conjugates.
- Packaged quantities suitable for lab-scale synthesis and conjugation workflows.
