Quality Control

Our Thiophene, 3,4-Dibutyl-2,5-Diiodo- is manufactured under strict quality management protocols. Every batch undergoes rigorous analytical testing including HPLC, GC, NMR, and elemental analysis to ensure identity, purity, and consistency. We provide comprehensive Certificates of Analysis (COA) with each shipment, detailing all critical specifications. Our quality systems are designed to support cGMP and ISO standards for research and development 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). Keep away from strong acids and incompatible organic solvents. Due to the presence of iodine substituents, which can be light-sensitive, ensure the container is opaque or stored in dark conditions.
