PEG

m-PEG-Mes, MW 10,000 is a monofunctional PEG with a good leaving group methanesulfonyl. The polymer can be used for nucleophilic SN2 substitution reaction. Reagent grade, for research purpose.

m-PEG-Tos, MW 5,000 is a tosylate (sulfonate ester) polyPEG for nucleophilic substitution reaction (SN2). Reagent grade, for research purpose.

m-PEG-Tos, MW 10,000 is a monofunctional PEG with a good leaving group, toluenesulfonyl. The polymer can be used for nucleophilic SN2 substitution reaction. Reagent grade, for research purpose.

HO-PEG-Tos, MW 3,400 is a polyPEG which can be further derivatized by nucleophilic subsitution (SN2) reaction. Reagent grade, for research purpose.

Tos-PEG-Tos, MW 3,000 is a tosylate (sulfonate ester) polyPEG for nucleophilic substitution reaction (SN2). Reagent grade, for research purpose.

Tos-PEG-Tos, MW 8,000 is a tosylates functional PEG polymer for SN2 reaction in the presence of a strong nucleophile. Reagent grade, for research purpose.

N-Boc-PEG8-bromide is a bifunctional PEG linker with a bromide and a Boc-protected amine. The bromide is a good leaving group which can be displaced by nucleophiles like amines or alcohols, while the Boc protecting group can be removed with strong acid.

t-boc-N-amido-PEG8-amine is a bifunctional PEG linker consisting of a Boc-protected amine and a free amine. The amine can be used to perform a variety of reactions such as coupling with carboxylic acids or reductive amination with aldehydes or ketones while the Boc can be deprotected for further reactions.

m-PEG-CH2CO2H, MW 10,000 is a PEG polymer with a terminal carboxylic acid group which can react with amino molecule in the presence of activator (e.g. EDC, or HATU) to form a covalent amide bond. Reagent grade, for research purpose.
