Lipids & Polymers

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.

Bis-PEG8-NHS ester is a homobifunctional PEG linker featuring two NHS esters, which that easily react with nucleophiles such as primary amines and alcohols to form amides or esters respectively.

Bis-PEG18-acid is a homobifunctional PEG linker featuring two carboxylic acids, which may be reacted with amines or alcohols.

Bis-PEG18-NHS ester is a homobifunctional PEG linker featuring two NHS esters, which easily react with nucleophiles such as primary amines and alcohols to form amides or esters respectively.

2-Octydecanoic acid is a saturated fatty acid with a long aliphatic tail consisting of 17 carbon atoms and a carboxylic acid group.
