Quality Control

Our 4'-Ethyl-Biphenyl-4-Carbonyl Chloride is manufactured under strict quality control protocols to ensure batch-to-batch consistency and high purity. Production adheres to cGMP guidelines where applicable. Each batch is accompanied by a comprehensive Certificate of Analysis (COA) detailing purity, identity, and impurity profiles, ensuring it meets the stringent requirements of pharmaceutical and advanced material applications.

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 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 strong acids, bases, and oxidizing agents.
