Quality Control

Our 2-Thiophenecarbonylchloride,3-Methoxy-5-Methyl-(9Ci) is produced and handled under a strict quality management system. Each batch undergoes rigorous analytical testing, including HPLC for purity and IR for structural confirmation, to ensure it meets precise customer specifications. A comprehensive Certificate of Analysis (COA) documenting all test results is provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (typically 15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent degradation.
