Quality Control

Our 3,4-Thiophenedicarbonyl Dichloride is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC for purity and IR for structural confirmation, to ensure it meets exacting specifications for sensitive synthetic applications. Certificates of Analysis (COA) with full traceability are provided for every shipment, supporting compliance in GMP-aligned environments.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated place at room temperature (15-25°C). Due to its reactivity as a strong acid/organic solvent derivative, keep away from moisture, strong bases, and oxidizing agents. Use appropriate corrosion-resistant storage materials.
