Quality Control

Our m-Toluoyl Chloride, 4-Propoxy- (7Ci) is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including chromatography (HPLC/GC) and spectroscopic methods (IR, NMR), to ensure high purity and consistent performance. A comprehensive Certificate of Analysis (COA) detailing identity, purity, and impurity profiles is provided with every shipment to support your quality assurance and regulatory documentation needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at a controlled room temperature (15-25°C). This compound is hygroscopic (moisture-sensitive) and reacts with strong acids/organic solvents; keep the container tightly sealed under an inert atmosphere (e.g., nitrogen or argon) for long-term storage to prevent degradation. Isolate from incompatible materials such as strong bases, oxidizing agents, and alcohols.
