PEGs are useful hydrophilic linkers for the bioconjugation. Diethyleneglycol, or PEG2, is a short PEG linker. This bifunctional molecule has an amino group that can be engaged in acylation reaction with anhydrides and activated esters, reductive amination with aldehydes and ketones, and alkylation with halogenides and epoxides, just to list a few reactions. Its terminal alkyne group reacts with azides in copper-catalyzed CuAAc reaction, and palladium-catalyzed Sonogashira coupling with aryl- and vinyl halides and triflates.

PEG是用于生物缀合的有用的亲水性接头。 二甘醇或 PEG2 是一种短 PEG 接头。 这种双功能分子具有一个氨基，可以与酸酐和活化酯进行酰化反应，与醛和酮进行还原胺化，与卤化物和环氧化物进行烷基化，仅举几例。 其末端炔基在铜催化的 CuAAc 反应中与叠氮化物反应，在钯催化的 Sonogashira 与芳基卤化物和乙烯基卤化物和三氟甲磺酸酯偶联。
