PEG

N-Methylaniline-PEG3-TCO is a short PEG linker featuring a methylaniline and a TCO group. TCO is a click chemistry handle which readily reacts with tetrazine-containing compounds while methylaniline is a highly electron-dense heterocycle with a variety of chemical applications.

N-Methylaniline-PEG3-methyltetrazine is a short PEG linker featuring a methylaniline and a methyltetrazine group. Methyltetrazine is a click chemistry motif which readily reacts with TCO-containing compounds while methylaniline is a highly electron-dense heterocycle with a variety of applications.

t-Boc-Aminooxy-PEG7-azide is a short bifunctional PEG linker featuring an azide and a Boc-protected amine. Azides readily react with alkynes through click chemistry, while the Boc protecting group can be removed using strong acid.

Dimethylanaline-PEG4-acid is a short PEG linker featuring a carboxylic acid and a methylaniline. Carboxylic acids can be linked to alcohols or amines while methylaniline is a highly electron-dense aromatic ring with a wide variety of chemical uses.

Bromo-PEG-bromide, MW 2,000 is a polyPEG linker containing two bromide groups. The bromide (Br) is a very good leaving group for nucleophilic substitution reactions. The hydrophilic PEG spacer increases solubility in aqueous media.

Azido-PEG5-azide is an aqueous soluble, homobifunctional PEG reagent. The azide (N3) group is very reactive with alkynes such as BCN, DBCO via Click Chemistry to yield a stable triazole moiety.

1-(2-hydroxymethyl)-1-H-pyrrole-2,5-dione is a synthetic building block for adding an maleimide group with a hydroxyl handle. The hydroxyl group enables further derivatization or replacement with other reactive functional groups. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

m-PEG-methyltetrazine, MW 2,000 is an aqueous soluble polyPEG click chemistry crosslinker. The methyl group improves the stability and the hydrophilic PEG spacer increases water-solubility. Methyltetrazine enables fast click reaction with TCO (trans-cycloctene).

m-PEG-methyltetrazine, MW 5,000 is an aqueous soluble polyPEG click chemistry crosslinker. The methyl group improves the stability and the hydrophilic PEG spacer increases water-solubility. Methyltetrazine enables fast click reaction with TCO (trans-cycloctene).
