Quality Control

Our Gyrophoric Acid is produced and handled under strict quality management protocols. Each batch undergoes rigorous analytical testing, including HPLC for purity verification and identity confirmation by spectroscopic methods (IR, NMR), to ensure it meets the high standards required for research and industrial use. A comprehensive Certificate of Analysis (COA) detailing all test results is provided with every shipment and is available upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at a controlled room temperature (15-25°C). Due to its light-sensitive nature and tendency to be easily oxidized, it is recommended to store the product under an inert atmosphere for long-term stability. Keep the container tightly sealed in a dry environment to minimize exposure to air and moisture.
