Quality Control

Our 2,7-Dihydroxy-3-Naphthaldehyde is manufactured under a strict quality management system. Every batch undergoes comprehensive analytical testing, including HPLC for purity and identity confirmation by FT-IR and NMR, to ensure it meets precise customer requirements and industry standards. A detailed Certificate of Analysis (COA) is provided with each shipment, documenting all critical quality parameters.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). Due to its light-sensitive and easily oxidized nature, it is recommended to handle under an inert atmosphere for long-term storage and to minimize headspace in opened containers.
