Quality Control

Our 10-Doxyl-Nonadecane is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including EPR spectroscopy to confirm radical purity and identity, and chromatographic methods to ensure chemical purity. A comprehensive Certificate of Analysis (COA) detailing assay, purity, and specific tests is provided with every shipment to guarantee consistency and compliance with your research specifications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at a controlled room temperature (15-25°C). For long-term stability, storing under an inert atmosphere (e.g., argon or nitrogen) is recommended to minimize potential radical degradation. Keep away from strong reducing agents.
