Quality Control

Our Benzonitrile, 4,5-Dichloro-2,3-Dihydroxy- (9Ci) is produced under strict quality management protocols. Each batch undergoes rigorous analytical testing to ensure identity, purity, and consistency. We provide comprehensive Certificates of Analysis (COA) with detailed results from techniques including HPLC, NMR, and IR spectroscopy. Our quality commitment ensures the material meets the exacting standards required 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). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) to prevent oxidation and moisture absorption. Keep away from incompatible materials.
