Quality Control

Our 4,5-Dichlorothiophene-2,3-Dicarbaldehyde is manufactured under strict quality management systems. Every batch undergoes rigorous analytical testing, including HPLC, NMR, and GC-MS, to ensure high purity and batch-to-batch consistency. A comprehensive Certificate of Analysis (COA) detailing identity, purity, and impurity profiles is provided with each shipment to support your quality assurance and regulatory needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated place at a controlled room temperature (15-25°C). Due to its sensitivity to oxidation, it is recommended to store the material under an inert atmosphere (e.g., nitrogen or argon) for long-term stability. Keep away from heat, sparks, and open flames.
