Quality Control

Our 3-Bromo-5-Ethoxy-4-Methoxybenzoyl Chloride is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC, NMR, and IR spectroscopy, to ensure high chemical purity and identity confirmation. Certificates of Analysis (COA) with detailed specifications are provided to guarantee consistency and traceability for your critical synthesis workflows.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated place at room temperature (15-25°C). Due to its hygroscopic and 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.
