Quality Control

Our 1,4-Naphthalenedione, 3-Chloro-5-Nitro-2-(Propylamino)- is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC for purity and identity confirmation via spectroscopic methods (IR, NMR), to ensure it meets exacting standards for research and industrial use. 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, and well-ventilated area at controlled room temperature (15-25°C). Keep away from heat, sparks, and open flame. Due to its light-sensitive nature, containers should be amber-colored or stored in light-resistant secondary packaging.
