Bis-PEG3-acid

 CAS No.: 96517-92-9  Cat No.: BP-500484  Purity: >95% 4.5  

Bis-PEG3-acid is a PEG linker containing two terminal carboxylic acid groups. The terminal carboxylic acids can react with primary amine groups in the presence of activators (e.g. EDC, or HATU) to form a stable amide bond. The hydrophilic PEG spacer increases solubility in aqueous media.
