Quality Control

Our 2-Naphthaldehyde is manufactured under strict quality management systems to ensure batch-to-batch consistency and high purity. Each lot is subjected to rigorous analytical testing, including HPLC, GC, and NMR, to verify identity, potency, and impurity profiles. A comprehensive Certificate of Analysis (COA) detailing all specifications is provided with every shipment. We adhere to cGMP principles where applicable to support our customers in regulated industries.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). Keep away from heat, sparks, and open flame. Due to its light-sensitive nature, containers should be kept in amber glass or opaque packaging during storage and handling.
