Quality Control

Every batch of 2-Thiophenecarboxylicacid,4-Fluoro-3-Methyl-(9Ci) is produced and tested under a strict quality management system. We provide comprehensive analytical data to ensure the material meets the high-purity standards required for research and cGMP manufacturing. A detailed Certificate of Analysis (COA) is supplied with each shipment, confirming identity, purity, and impurity profiles as determined by HPLC, NMR, and other spectroscopic methods.

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). This product is hygroscopic (moisture-sensitive) and light-sensitive; therefore, containers must be kept tightly sealed and under an inert atmosphere (e.g., nitrogen or argon) for long-term storage to prevent degradation.
