Quality Control

Our Piperonyl Chloride is manufactured under strict quality management systems to ensure batch-to-batch consistency and high purity. Each lot undergoes comprehensive analytical testing, including HPLC for assay and impurity profiling, IR for structural confirmation, and GC for residual solvent analysis. A detailed Certificate of Analysis (COA) is provided with every shipment, confirming compliance with agreed specifications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area away from incompatible materials such as strong bases, oxidizing agents, and moisture. Recommended storage temperature is between 15°C and 25°C. Due to its reactivity as an acid chloride, ensure containers are kept tightly sealed under an inert atmosphere (e.g., nitrogen) for long-term storage to prevent hydrolysis.
