Quality Control

Our (-)-α-(2,4,5,7-Tetranitro-9-Fluorenylideneaminoxy)Propionic Acid is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including chiral purity verification, to ensure it meets the high standards required for research and process chemistry. Certificates of Analysis (COA) detailing identity, purity, and chiral excess are available upon request to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at a controlled room temperature (15-25°C). Due to its light-sensitive and easily oxidized nature, it is recommended to store this material under an inert atmosphere (e.g., nitrogen or argon) for long-term stability. Keep away from heat, sparks, and open flame.
