Quality Control

Our 2-Naphthalenecarboxylic Acid, 6,7-Dihydroxy- (9Ci) is produced under a strict quality management system. Each batch undergoes rigorous analytical testing to ensure identity, purity, and consistency. Certificates of Analysis (COA) detailing specific results for purity, related substances, and other critical parameters are provided with every shipment. We support custom purity requirements for research and industrial applications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated place at room temperature (15-25°C). Due to its sensitivity to oxidation, prolonged storage under an inert atmosphere (e.g., nitrogen or argon) is recommended for optimal long-term stability. Keep away from incompatible materials.
