Quality Control

Every batch of 2,8-Thianthrenedicarboxylic Acid is produced and tested under a strict quality management system. We ensure compliance with high-purity standards suitable for research and industrial synthesis. Comprehensive analytical testing, including HPLC for purity and NMR for structural confirmation, is performed. A Certificate of Analysis (COA) detailing batch-specific results is provided with each shipment to guarantee traceability and consistency.

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 by atmospheric moisture.
