Quality Control

Our 2-Amino-1,4-Naphthoquinone Hemihydrate is manufactured under a strict quality management system. Each batch undergoes comprehensive analytical testing, including HPLC for purity and identity confirmation by FT-IR and melting point, to ensure it meets the high standards required for research and industrial synthesis. Certificates of Analysis (COA) documenting all critical parameters 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 place at a controlled room temperature (15-25°C). Due to its light-sensitive and easily oxidized nature, it is recommended to store the product under an inert atmosphere for long-term stability and to minimize decomposition.
