Quality Control

Our 4-Hydrazino-3-Hydroxy-Naphthalene-2-Carboxylic Acid is produced under strict quality management protocols. Every batch undergoes comprehensive analytical testing, including HPLC for purity and identity confirmation, to ensure it meets the high standards required for research and industrial synthesis. A Certificate of Analysis (COA) detailing all specifications is provided with each shipment and is available upon request.

Storage

Preserve in a tightly closed container, protected from light. Due to its hygroscopic (moisture-sensitive) nature, store under an inert atmosphere such as nitrogen or argon in a cool, dry place. Recommended long-term storage temperature is 2-8°C. Allow the container to reach room temperature before opening to minimize moisture ingress.
