Polyethylene Glycol (PEGs & PEOs)

t-Boc-N-amido-PEG10-acid is a PEG derivative containing a terminal carboxylic acid and Boc-protected amino group. The hydrophilic PEG spacer increases solubility in aqueous media. The terminal carboxylic acid can be reacted with primary amine groups

t-Boc-N-amido-PEG10-NHS ester is a PEG derivative containing an NHS ester and a Boc-protected amine group. The hydrophilic PEG spacer increases the water solubility of a compound in aqueous media. The Boc group can be deprotected under mild acidic

t-Boc-N-amido-PEG10-NHS ester is a PEG derivative containing an NHS ester and a Boc-protected amine group. The hydrophilic PEG spacer increases the water solubility of a compound in aqueous media. The Boc group can be deprotected under mild acidic

t-Boc-N-amido-PEG10-NHS ester is a PEG derivative containing an NHS ester and a Boc-protected amine group. The hydrophilic PEG spacer increases the water solubility of a compound in aqueous media. The Boc group can be deprotected under mild acidic

t-Boc-N-amido-PEG11-amine is a PEG derivative containing an amino group and Boc-protected amino group. The hydrophilic PEG spacer increases solubility in aqueous media. The amino group is reactive with carboxylic acids, activated NHS esters,
