N-(Azido-PEG4)-N-bis(PEG4-t-butyl ester)
blur_circular Chemical Specifications
description Product Description
Used extensively in bioconjugation and click chemistry applications, this compound serves as a versatile linker for attaching biomolecules. Its azide group enables efficient and selective reactions with alkynes, facilitating the creation of stable triazole linkages. The PEG4 spacers enhance solubility and reduce steric hindrance, making it ideal for modifying proteins, peptides, and other biomolecules. The t-butyl ester groups provide protection, allowing controlled deprotection for further functionalization. It is particularly valuable in drug delivery systems, where it aids in the development of targeted therapies by linking therapeutic agents to carriers or antibodies. Additionally, it is employed in the synthesis of complex polymers and nanomaterials, enabling precise control over molecular architecture.
