Quality Control

Our Tetrahydro-5-Ethylidene-4-(2-Hydroxyethyl)-2H-Pyran-2-One is produced under strict quality management protocols. Each batch undergoes rigorous analytical testing to ensure identity, purity, and consistency. Certificates of Analysis (COA) detailing specific results for assay and impurity profiles are available upon request. We are committed to meeting the stringent requirements of research and industrial applications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after each use to prevent degradation. Keep away from strong bases and incompatible materials.
