endo-BCN-PEG4-t-butyl ester
This producct is a heterobifunctional linker containing an endo-bicyclononyne (BCN) group for copper-free SPAAC click chemistry and a t-butyl ester as an acid-labile protecting group. The PEG4 spacer specifically enhances solubility, flexibility, and spacing, making it ideal for bioconjugation, probe development, and drug delivery.
Key Features and Benefits:
-
Endo-BCN Group: Enables rapid copper-free click chemistry with azides.
-
t-Butyl Ester: Provides acid-labile protection for controlled deprotection.
-
PEG4 Spacer: Enhances solubility, hydrophilicity, and steric accessibility.
-
Orthogonal Reactivity: Supports multi-step synthesis and controlled conjugation.
-
High Purity: Ensures reproducibility in advanced workflows.
Applications:
-
Bioconjugation: Combines SPAAC click chemistry with protected ester functionality.
-
Drug Delivery: Builds PEGylated scaffolds with controlled release strategies.
-
Probe Development: Enables BCN-modified probes with orthogonal handles.
-
Material Science: Functionalizes surfaces, polymers, and nanoparticles.
Storage and Handling:
-
Storage: Store at –20 °C in a sealed, light- and moisture-protected container.
-
Handling: Use anhydrous solvents (e.g., DMF, DMSO); avoid premature deprotection of t-butyl ester.
This product integrates bioorthogonal BCN reactivity with a protected ester in a PEG4 scaffold, specifically offering versatility for controlled conjugation and multifunctional design.
