H2N-PEG2-CH2COOtBu features a short PEG spacer linking a primary amine to a tert-butyl ester, enabling selective conjugation under mild conditions. This bifunctional scaffold supports efficient coupling reactions while the protected carboxyl group remains stable during handling and storage.
H2N-PEG2-CH2COOtBu serves as a versatile bifunctional building block for peptide and protein conjugation, combining a stable tert-butyl ester with a terminal primary amine. The PEG2 spacer enhances solubility and reduces aggregation, while the ester group enables selective coupling under mild conditions. This reagent facilitates efficient solid-phase synthesis and bioconjugation workflows, offering excellent bench stability and straightforward purification.
