Quality Control

Our products undergo rigorous quality testing to ensure compliance with industry standards for research and development use. We employ advanced analytical techniques including HPLC, NMR, and mass spectrometry to verify identity, purity, and consistency. Certificates of Analysis (COA) are available upon request, detailing batch-specific results for all critical parameters.

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 sensitivity, the container should be kept under an inert atmosphere (e.g., nitrogen or argon) to prevent oxidation. Keep away from heat, sparks, and open flame.
