Quality Control

Our (Alpha,γ-Bisdiphenylene-β-Phenylallyl), Free Radical is produced and handled under strict quality protocols to ensure batch-to-batch consistency and high radical purity. Each lot is characterized by multiple analytical techniques to confirm identity and assess stability. Certificates of Analysis (COA) detailing purity, assay, and relevant spectroscopic data are provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Due to its sensitivity to oxygen and light, this material should be stored under an inert atmosphere (e.g., argon or nitrogen) at a controlled room temperature (15-25°C). Keep the container tightly sealed in a cool, dry, and well-ventilated place away from incompatible materials.
