Quality Control

Our 2,7-Dihydroxynaphthalene-1-Carbaldehyde is produced under stringent quality management protocols. Every batch is analyzed to ensure high chemical purity and consistency. We provide comprehensive Certificates of Analysis (COA) with each shipment, detailing key parameters such as assay, identity, and impurity profiles. Our quality systems are designed to support cGMP and ISO standards for reliable supply to regulated industries.

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 light-sensitive and easily oxidized nature, prolonged exposure to light and air should be minimized. For long-term storage, consider an inert atmosphere.
