Cbz-N-amido-PEG20-acid is a PEG linker containing a Cbz-protected amino 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 hydrophilic PEG spacer increases solubility in aqueous media. The protected amine can be deprotected by acidic conditions. Please contact us for GMP-grade inquiries.
