Quality Control

We maintain a rigorous quality management system to ensure batch-to-batch consistency and high purity. Our products undergo comprehensive analytical testing, including chromatography (GC/HPLC) and spectroscopy (IR, NMR), to verify identity and purity against established specifications. A Certificate of Analysis (COA) detailing all test results is provided with each shipment and is available upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area. Due to its highly volatile nature, keep containers tightly sealed when not in use and away from heat sources and open flames. Recommended storage temperature is 2-8°C for long-term stability.
