Quality Control

Our 4,6-Dichloro-2-Methyl-2H-1-Benzothiine-3-Carbaldehyde 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. Certificates of Analysis (COA) documenting all critical quality parameters are available upon request, supporting your regulatory and R&D documentation needs.

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. Keep away from incompatible materials.
