Description

1-Azido-3,6,9-Trioxaundecane-11-Ol is a specialized bifunctional organic compound featuring a reactive azide group and a terminal hydroxyl group, linked by a flexible triethylene glycol spacer. This unique structure makes it a valuable heterobifunctional crosslinker and building block for click chemistry applications, enabling the efficient and selective conjugation of biomolecules and polymers. It is primarily utilized by researchers and manufacturers in the pharmaceutical, bioconjugation, and advanced materials sectors for developing targeted drug delivery systems, diagnostic probes, and functionalized surfaces.

Application

• As a key reagent in Cu(I)-catalyzed azide-alkyne cycloaddition (CuAAC) click chemistry for bioconjugation.
• Functionalization of nanoparticles, surfaces, and polymers to introduce bio-recognition elements or specific properties.
• Synthesis of PEG-based linkers and prodrugs for pharmaceutical R&D and drug delivery system development.
• Preparation of affinity chromatography resins and biosensor platforms.
• Crosslinking agent for hydrogel formation and biomaterial engineering.
• Intermediate in the synthesis of more complex chemical probes and labeled compounds.

Quality Control

Our 1-Azido-3,6,9-Trioxaundecane-11-Ol is produced under strict quality management protocols. Each batch undergoes comprehensive analytical testing, including HPLC, NMR, and FT-IR, to ensure high purity and consistent performance for sensitive applications like bioconjugation. A detailed Certificate of Analysis (COA) is provided with every shipment, confirming identity, purity, and absence of critical impurities.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at 2-8°C under an inert atmosphere (e.g., nitrogen or argon) to minimize oxidation and degradation due to its light-sensitive and easily oxidized nature. Keep away from heat, sparks, and open flame. For long-term storage, consider freezing at -20°C.
