Quality Control

Our 3,5-Diiodosalicyloyl Chloride is manufactured under strict quality control protocols to ensure batch-to-batch consistency and high purity. We employ advanced analytical techniques including HPLC, NMR, and IR spectroscopy for comprehensive characterization. A Certificate of Analysis (COA) detailing purity, identity, and impurity profiles is provided with each shipment, supporting compliance with cGMP and ISO 9001 standards where applicable.

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) after opening to prevent decomposition. Keep away from heat, open flames, and incompatible materials such as strong bases, alcohols, and water.
