Description

tert-Butyl-3,6,9,12,15,18,21-Heptaoxadotriacont-31-Enoate is a specialized polyethylene glycol (PEG)-based ester compound featuring a terminal tert-butyl ester group and an unsaturated alkene moiety. This unique bifunctional structure makes it a valuable intermediate for the synthesis of advanced materials and bioconjugates, offering orthogonal reactivity for polymer modification and linker chemistry. It is primarily utilized by researchers and manufacturers in the pharmaceutical, biotechnology, and advanced materials sectors for applications requiring precise molecular design and controlled functionalization.

Application

• Pharmaceutical Linker Chemistry: Serves as a versatile heterobifunctional linker for the conjugation of drug molecules, peptides, or imaging agents to PEG-based carriers, enabling controlled drug delivery systems.
• Polymer Functionalization: Acts as a reactive macromonomer or chain-transfer agent for introducing terminal alkene or protected carboxylic acid groups into polymer backbones, facilitating further cross-linking or modification.
• Surface Modification: Used to create functionalized surfaces on nanoparticles, biosensors, or medical devices by exploiting the alkene group for "click" chemistry or thiol-ene reactions.
• Bioconjugation Intermediate: Provides a protected carboxylic acid handle (as the tert-butyl ester) for subsequent deprotection and coupling to amines or other nucleophiles on biomolecules like proteins or antibodies.
• Hydrogel Synthesis: Employed as a cross-linking agent or functional precursor in the development of hydrogels for tissue engineering and controlled release applications.
• Lipid Nanoparticle (LNP) Formulation: Can be incorporated as a functionalizable PEG-lipid component to tailor the surface properties and targeting capabilities of LNPs for mRNA and gene delivery.
