Quality Control

Our 2,3-Dihydro-3,5-Dihydroxy-6-Methyl-4(H)-Pyran-4-One is produced under strict quality management systems. We offer grades compliant with FCC (Food Chemicals Codex) for food applications and high-purity grades for pharmaceutical synthesis. Every batch undergoes rigorous analytical testing, including HPLC and GC analysis, to ensure identity, purity, and consistency. Certificates of Analysis (COA) are available 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 absorption of moisture from the air.
