Quality Control

Our 4,5-Dichlorothiophene-2-Carboxylic Acid is manufactured under strict quality management systems. Every batch undergoes rigorous analytical testing, including HPLC, NMR, and GC-MS, to ensure identity, purity, and consistency. We provide comprehensive Certificates of Analysis (COA) with each shipment, detailing all critical quality attributes. Our commitment to quality supports applications in regulated research and development environments.

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 nature, the container must be kept tightly sealed to prevent moisture absorption, which can affect stability and handling properties. Keep away from incompatible materials such as strong bases and oxidizing agents.
