Quality Control

Our Oxidane is produced and tested under stringent quality management systems. We offer various grades, including high-purity and NMR-grade specifications, with a focus on isotopic enrichment and chemical purity. Each batch is accompanied by a comprehensive Certificate of Analysis (COA) detailing key parameters such as isotopic purity (D atom %), conductivity, and trace metal content to ensure it meets the rigorous demands of research and industrial applications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). Due to its hygroscopic nature, containers should be kept tightly sealed to prevent absorption of atmospheric moisture and ordinary water vapor, which can alter the isotopic purity.
