- Description
Mal-PEG4-COOH is a bifunctional PEG linker bearing a maleimide group and a terminal carboxylic acid. Its hydrophilic PEG spacer enhances aqueous solubility. The maleimide reacts with thiol groups to create stable covalent attachments, while the carboxylic acid can form amide bonds with primary amines using activators such as EDC or HATU.
These complementary coupling groups support bioconjugation workflows. The product is listed in the ADC linker and functionalized PEG categories, with a molecular formula of C15H23NO8, molecular weight of 345.3 and purity of ≥95%.
