Quality Control

Our 3-Aminonaphthalene-2-Carboxylic Acid Methyl Ester is manufactured under strict quality management systems. Every batch undergoes rigorous analytical testing, including HPLC for purity and identity confirmation, to ensure it meets the high standards required for synthetic applications. Certificates of Analysis (COA) documenting all critical parameters are provided with each shipment to guarantee traceability and batch-to-batch consistency for our global B2B clients.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (typically 15-25°C). Keep away from heat, sparks, and open flame. Due to its light-sensitive nature, the container should be opaque or stored in dark conditions.
