Quality Control

Our products undergo rigorous quality testing to ensure compliance with industry standards for high-purity intermediates. Each batch is characterized using advanced analytical techniques including HPLC, NMR, and IR spectroscopy to confirm identity and purity. Certificates of Analysis (COA) detailing all specifications are available upon request to support your quality assurance and regulatory needs.

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). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) to prevent decomposition. Keep away from strong acids and incompatible materials.
