Quality Control

Our products undergo rigorous quality testing to ensure compliance with industry standards for high-purity intermediates. Each batch is analyzed using advanced techniques like GC, HPLC, and NMR to verify identity, purity, and consistency. Certificates of Analysis (COA) are available upon request, providing full transparency on all critical parameters to support your quality assurance and regulatory needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, well-ventilated area away from strong bases and incompatible materials. Due to its highly volatile nature, keep containers tightly sealed when not in use. Recommended storage temperature is 2-8°C for long-term stability, though short-term storage at 15-25°C is acceptable.
