PLLA-Azide (PLLA-N3), MW 5K is an azide-functionalized poly(L-lactide) with a molecular weight of approximately 5K. It combines a low-molecular-weight biodegradable PLLA backbone with terminal azide functionality specifically for click chemistry, bioconjugation, polymer functionalization, nanoparticle modification, and biomaterial research.
Key Features and Benefits
- Azide-Functionalized PLLA: Combines biodegradable poly(L-lactide) with a terminal azide group for chemical modification and conjugation.
- MW 5K: Provides a low molecular weight with good processability specifically for polymer functionalization, formulation, and conjugation research.
- Azide Functionality: The terminal –N3 group provides a reactive site specifically for azide-alkyne click chemistry and related conjugation strategies.
- Biodegradable Polyester: The PLLA backbone contains hydrolyzable ester linkages that support gradual polymer degradation under appropriate conditions.
- Stereoregular PLLA Backbone: The L-lactide-derived polymer structure promotes crystallinity and provides especially useful polymer properties.
- Good Processability: The lower molecular weight facilitates polymer dissolution, formulation, and chemical modification compared with higher-molecular-weight PLLA grades.
- Click Chemistry Platform: The azide terminus supports Cu(I)-catalyzed azide-alkyne cycloaddition (CuAAC) with terminal alkynes.
- Copper-Free Conjugation: The azide group supports strain-promoted azide-alkyne cycloaddition (SPAAC) with compatible strained cyclooctynes.
Applications
- CuAAC Click Chemistry: Supports conjugation with terminal alkyne-functionalized molecules, polymers, and surfaces.
- Copper-Free Click Chemistry: Supports SPAAC reactions with DBCO, BCN, and other compatible strained cyclooctyne-functionalized components.
- Bioconjugation: Provides terminal azide functionality for coupling PLLA with compatible biomolecules and functional ligands.
- Polymer Functionalization: Enables preparation of functional PLLA derivatives and more complex polymer architectures.
- Nanoparticle Functionalization: Supports preparation and surface modification of biodegradable polymer nanoparticles and related delivery systems.
- Drug Delivery: Supports development of functional biodegradable polymer systems for drug-delivery and controlled-release research.
- Surface Modification: Enables attachment of PLLA to compatible alkyne- or cyclooctyne-functionalized surfaces and materials.
- Biomaterial Research: Supports development of functional biodegradable polymers, particles, coatings, composites, and related biomaterials.
Storage and Handling
- Storage: Store at –20 °C in a tightly sealed container under dry conditions. Protect from moisture and excessive heat.
- Handling: Protect from moisture and excessive heat. Allow the material to equilibrate to room temperature before opening to minimize moisture condensation.
