Quality Control

Our 4H-Pyran-4-One, 2-Chloro-3-Hydroxy-6-(Hydroxymethyl)- is produced under a strict quality management system. Every batch undergoes comprehensive analytical testing, including HPLC, NMR, and IR spectroscopy, to ensure identity, purity, and consistency. Certificates of Analysis (COA) documenting all critical parameters are available upon request, providing full traceability and compliance with your internal quality standards.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at a controlled 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.
