Description

Methyl 10-Doxyl-Stearate is a spin-labeled fatty acid ester, specifically a stearic acid derivative bearing a stable nitroxide radical (doxyl) reporter group at the 10th carbon position. This compound is a critical research tool in biophysics and materials science, enabling the study of molecular dynamics, membrane fluidity, and polymer properties through techniques like Electron Paramagnetic Resonance (EPR) spectroscopy. It is essential for researchers and R&D teams in pharmaceutical development, advanced polymer synthesis, and fundamental biochemical research who require precise probes for investigating lipid bilayer systems and soft matter interfaces.

Application

• As a spin probe for Electron Paramagnetic Resonance (EPR) spectroscopy to study membrane fluidity and lipid dynamics.
• Research tool for investigating lipid-protein interactions and the structure of model biological membranes.
• Probe for analyzing polymer chain mobility and microstructure in advanced materials science.
• Use in biophysical studies to understand oxidative stress and free radical processes in lipid systems.
• Component in the development of advanced diagnostic assays and sensor technologies.
• Tool for molecular dynamics simulations and model validation in computational chemistry.

Quality Control

Our Methyl 10-Doxyl-Stearate is produced under strict quality management protocols to ensure high purity and batch-to-batch consistency, critical for sensitive spectroscopic applications. Each lot undergoes comprehensive analysis, including HPLC for purity assessment and EPR to verify radical integrity and concentration. A detailed Certificate of Analysis (COA) is provided with every shipment, documenting key parameters. We support research and development requiring traceable, high-quality specialty chemicals.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at 2-8°C (refrigerated) for long-term stability. This product is hygroscopic (moisture-sensitive); ensure the container is sealed under an inert atmosphere (argon or nitrogen) after each use to prevent degradation of the nitroxide radical. Keep away from strong reducing agents.
