Description

n-Triethoxysilylpropylquinineurethan is a specialized organosilane coupling agent that incorporates a quinine-derived urethane functional group. This unique molecular structure makes it a critical component for imparting specific optical, chiral, or bioactive properties to modified surfaces and materials. It is essential for researchers and manufacturers in advanced material science who require precise surface functionalization. This compound, CAS NO 200946-85-6, is particularly valuable for creating hybrid organic-inorganic interfaces with tailored characteristics.

Application

• Chiral Stationary Phases (CSPs): Key intermediate for synthesizing silica-based HPLC columns used in enantiomeric separation of pharmaceuticals and fine chemicals.
• Advanced Composite Materials: Acts as a coupling agent to improve adhesion between inorganic fillers (like glass or silica) and organic polymer matrices in high-performance composites.
• Surface Modification of Nanoparticles: Used to functionalize silica, metal oxide, or quantum dot surfaces to introduce chirality, bioactivity, or specific binding sites for sensor applications.
• Optical Materials: Serves as a precursor for sol-gel derived thin films and coatings with potential non-linear optical (NLO) or light-guiding properties.
• Bioconjugation and Immobilization: Facilitates the covalent attachment of biomolecules, such as enzymes or antibodies, to solid supports for biosensor and diagnostic device development.
• Antimicrobial Coatings: The quinine moiety can contribute to surface modifications aimed at creating antimicrobial or antifouling coatings for medical devices.

Quality Control

Our n-Triethoxysilylpropylquinineurethan is produced under strict quality management protocols to ensure batch-to-batch consistency and high purity for research and industrial applications. Each lot is characterized by advanced analytical techniques including NMR, HPLC, and FTIR to confirm identity and purity. A comprehensive Certificate of Analysis (COA) detailing all specifications is provided with every shipment to support your quality assurance and regulatory needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent degradation by moisture.
