PEG Azide or Azido PEG is widely used in Click Chemistry, with this particular example of the Cu(I) catalyzed reaction between the azide and a terminal acetylene and also the Staudingerligation using functionalized aryl phosphines to couple to the azide, forming amides.

Azido-PEG5-azide is a PEG-based PROTAC linker that can be used in the synthesis of PROTACs. Azido-PEG5-azide is a click chemistry reagent, it contains an Azide group and can undergo copper-catalyzed azide-alkyne cycloaddition …

Azido-PEG2-C2-amine 是一种点击化学试剂。 它含有 Azide 基团，可以和含有 Alkyne 基团的分子发生铜催化的叠氮-炔环加成反应（CuAAc)。 它还可以和含有 DBCO 或 BCN 基团的分子发生环张力驱动的炔-叠氮环加成反应 (SPAAC)。

Azide Linkers and Azide PEG (Azido PEG) are highly popular in click chemistry, bioconjugation, and drug discovery. They participate in efficient reactions with alkynes to form stable 1,2,3-triazoles, which closely resemble amide bonds. Their small size has minimal impact on biomolecule activity, allowing precise functionalization.

Azido-PEG2-DNP 是一种具有叠氮（Azido）功能基团的聚乙二醇（PEG）衍生物，并且在分子中包含了2,4-二硝基苯胺（DNP）基团。其结构的关键特点是：PEG链上连接着一个叠氮基团和一个DNP分子。叠氮基团使该分子在化学反应中具备反应性，可以参与无铜的点击化学反应（SPAAC），与带有环炔（alkyne）基团的 ...

Amino-PEG3-azide is a bifunctional PEG linker containing an amino group and an azide group. The hydrophilic PEG spacer increases solubility in aqueous media. The amino group is reactive with carboxylic acids, activated NHS esters, carbonyls (ketone, aldehyde) etc.

Azido-PEG3-NHS ester is a azide linker used on click chemistry. The azide group can react with alkyne such as BCN, DBCO, Propargyl group via Click Chemistry to yield a stable triazole linkage. The NHS ester can be applied to label the primary amines (-NH2) of proteins, amine-modified oligonucleotides, and other amine-containing molecules.

Azido-PEG4-NHS Ester is a labeling reagent that can be used to modify primary amine groups (e.g., a side chain of lysine residues or aminosilane-coated surfaces) with an azido group via a stable amide bond.

2025年2月28日 · Azido-PEG4-NHS is an amine-reactive crosslinker specifically engineered to facilitate efficient and flexible bioconjugation and bio-orthogonal labeling in complex biological systems. This reagent contains an N-hydroxysuccinimide (NHS) ester, which selectively and efficiently reacts with primary amines on proteins, peptides, or amine ...
