Quality Control

Our products undergo rigorous quality testing to ensure compliance with industry standards. Each batch is analyzed using advanced techniques such as HPLC, GC, NMR, and IR spectroscopy to confirm identity, purity, and the absence of critical impurities. Certificates of Analysis (COA) detailing all specifications and test results are available upon request. We adhere to a strict quality management system to guarantee batch-to-batch consistency and reliability for your critical research and development processes.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at a controlled room temperature (15-25°C). This compound is hygroscopic (moisture-sensitive) and should be handled under an inert atmosphere (e.g., nitrogen or argon) to prevent decomposition. Keep away from strong acids, bases, and oxidizing agents.
