PEG

t-Boc-N-Amido-PEG1-amine is a small molecule PEG reagent containing an amino group and Boc-protected amino group. The amino group is reactive with carboxylic acids, activated NHS esters, carbonyls (ketone, aldehyde) etc. The Boc group can be deprotected under mild acidic conditions to form the free amine. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

Cbz-N-amido-PEG10-acid is a PEG linker containing a CBZ-protected amino group and a terminal carboxylic acid. The terminal carboxylic acid can react with primary amine groups in the presence of activators (e.g. EDC, or HATU) to form a stable amide bond. The hydrophilic PEG spacer increases solubility in aqueous media. The protected amine can be deprotected by acidic conditions. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

N-Boc-PEG8-alcohol is a PEG linker containing a hydroxyl group and Boc-protected amino group. The hydrophilic PEG spacer increases solubility in aqueous media. The hydroxyl group enables further derivatization or replacement with other reactive functional groups. The Boc group can be deprotected under mild acidic conditions to form the free amine. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

Hydroxy-PEG2-sulfonic acid is a PEG linker containing hydroxyl and sulfonic acid moieties. The hydroxyl group can react to further derivatize the compound. The sulfonic acid group can participate in esterification, halogenation and replacement reactions. The hydrophilic PEG linkers increase the water solubility of the compound in aqueous media. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

Benzyl-PEG5-azide is a PEG linker containing a benzyl protecting group and an azide moiety. Benzyl is an alcohol protecting group which can be removed via hydrogenolysis. The azide moiety can participate in copper-catalyzed Click Chemistry reactions with alkynes, DBCO and BCN. The hydrophilic PEG spacer increases the water solubility of compounds in aqueous media. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

Benzyl-PEG5-amine is a PEG linker containing a benzyl protecting group and a free terminal amine. Benzyl groups are used to protect alcohol moieties and can be removed via hydrogenolysis. The primary amine can react with carboxylic acids, activated NHS esters and other carbonyl compounds. The hydrophilic PEG linkers increase the water solubility of a compound in aqueous media. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

Bromoacetamido-PEG2-azide is a heterobifunctional PEG linker containing a reactive bromoacetamido and a terminal azide.The bromoacetamidogroup is a very reactive group for nucleophilic substitution. The azide group can react with alkyne, BCN, DBCO via Click Chemistry. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.
