Quality Control

Our 7-Oxo-5-Trifluoromethyl-7-H-Thieno-3,2-Pyran-3-Carboxylic Acid is manufactured under a strict quality management system. Every batch undergoes rigorous analytical testing to ensure high purity, identity, and consistency, meeting the stringent requirements for research and process development. Certificates of Analysis (COA) detailing purity, assay, and impurity profiles are available upon request.

Storage

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