Quality Control

Our 2H-Pyran-3-Carbonyl Chloride, 6-Chloro-4-Hydroxy-2-Oxo- (8Ci,9Ci) is produced under strict quality management protocols. Each batch undergoes rigorous analytical testing, including HPLC for purity and identity confirmation, to ensure it meets the high standards required for research and process chemistry. Certificates of Analysis (COA) detailing batch-specific results are available upon request to support your quality assurance and regulatory documentation.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated place at a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature and reactivity as a strong acid/organic solvent derivative, the container must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent degradation. Keep away from heat, sparks, and open flame.
