COOH-PEG1-COOtBu

 CAS No.: 2086689-08-7  Cat No.: BP-500860  Purity: ≥95% 4.5  

COOH-PEG1-COOtBu is a PEG linker containing a t-butyl-protected carboxyl group and a terminal carboxylic acid. The terminal carboxylic acid can react with primary amine groups in the presence of activators (e.g. EDC, or HATU) to form a stable amide bond. The t-butyl-protected carboxyl group can be deprotected under acidic conditions. The hydrophilic PEG spacer increases solubility in aqueous media.
