Quality Control

Our Aluminum 3-Hydroxy-2-Methyl-4-Pyronate is manufactured under a strict quality management system. Each batch is tested to ensure it meets precise specifications for identity, purity, and metal content. A comprehensive Certificate of Analysis (COA) is provided with every shipment, detailing results from advanced analytical techniques. We can support compliance requirements for various application standards upon request.

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). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after opening to prevent degradation from atmospheric moisture.
