Quality Control

Our Sodium 3-Hydroxy-n-Naphthylnaphthalene-2-Carboxamidate is manufactured under a strict quality management system. The product undergoes rigorous analytical testing to ensure batch-to-batch consistency and meets high-purity standards suitable for pigment synthesis. Certificates of Analysis (COA) detailing purity, identity, and impurity profiles 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, well-ventilated area at a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after opening to prevent degradation from atmospheric moisture.
