Quality Control

Our Benzoylchloride,2,3,4,5-Tetramethyl-(9Ci) is produced under strict quality management protocols. Each batch undergoes comprehensive analytical testing, including chromatography and spectroscopy, to ensure high purity and consistency suitable for research and industrial synthesis. A Certificate of Analysis (COA) detailing purity, identity, and impurity profiles is provided with every shipment to guarantee traceability and compliance with your project specifications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at 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 degradation. Keep away from strong bases, oxidizers, and moisture.
