Product Name:CbzNH2-PEGn-CH2COOH
CbzNH2-PEGn-CH2COOH is a series of PEG linkers containing a Cbz-protected amine and a terminal carboxylic acid. CbzNH2-PEGn-CH2COOH has been wildly used in the synthesis of peptides and other applications. It is an acylated form of the amino acid cysteine (Cys) and is composed of a cysteine-based amino acid, a polyethylene glycol (PEG) chain, and a carboxyl group with a high degree of flexibility and stability, making it an ideal choice for use in a variety of research and industrial applications, including drug delivery, enzyme catalysis, and bioconjugation.
The terminal carboxylic acid is reactive with primary amine groups in the presence of activators (e.g. EDC, or HATU) forming a stable amide bond. The benzyl protecting group can be removed via hydrogenolysis to form a free amine.
