Description

Bromo-Peg3-Azide is a heterobifunctional polyethylene glycol (PEG) linker featuring a reactive bromo group and a terminal azide. This compound is essential for creating stable, well-defined bioconjugates and materials through orthogonal click chemistry and nucleophilic substitution reactions. It is primarily used by researchers and manufacturers in the pharmaceutical, biotechnology, and materials science industries for applications such as antibody-drug conjugate (ADC) development, polymer functionalization, and surface modification.

Application

• Key reagent in the synthesis of Antibody-Drug Conjugates (ADCs) and other targeted therapeutics.
• Functional linker for polymer modification and cross-linking in advanced material design.
• Tool compound for bioconjugation strategies, enabling the attachment of dyes, drugs, or other molecules to biomolecules.
• Intermediate in the development of PEGylated prodrugs and delivery systems to enhance solubility and pharmacokinetics.
• Building block for creating functionalized surfaces and hydrogels for diagnostic assays and biosensors.
• Used in chemical biology research for labeling and studying biomolecular interactions.
