Quality Control

Our Naphtho[2,3-B]Furan-3-One is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC for purity and identity confirmation via spectroscopic methods, to ensure it meets precise customer specifications and high industry standards. Certificates of Analysis (COA) documenting all critical quality attributes are available upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at a controlled room temperature (typically 15-25°C). Keep away from incompatible materials. Due to its light-sensitive nature, containers should be kept in the original opaque packaging or amber glass until use.
