Quality Control

Our 2-Thiopheneacetic Acid, 3-Amino- is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC, NMR, and FTIR, to ensure identity, purity, and consistency. Certificates of Analysis (COA) detailing all specifications are provided with every shipment to guarantee reliable performance in your critical synthesis applications.

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. For long-term storage, consider using desiccants.
