Quality Control

Our 2-Naphthalenecarboxylic Acid, 3,4-Dihydroxy- (9Ci) is produced under strict quality management protocols. Each batch undergoes comprehensive analytical testing, including HPLC for purity and identity confirmation via FT-IR and NMR, to ensure it meets the stringent requirements of research and industrial synthesis. A Certificate of Analysis (COA) detailing all specifications is provided with every shipment to guarantee traceability and compliance with your internal quality standards.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and 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 material under an inert atmosphere (e.g., nitrogen or argon) for long-term preservation to maintain optimal purity and stability. Keep away from strong oxidizing agents.
