Quality Control

Our products undergo rigorous quality testing to ensure compliance with industry standards. Each batch is characterized to confirm identity, purity, and consistency. Certificates of Analysis (COA) detailing specific results for parameters such as assay, impurities, and residual solvents are available upon request. We adhere to strict internal quality management protocols to ensure supply reliability for your critical R&D and scale-up projects.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed and may require storage under an inert atmosphere for long-term stability. Keep away from heat and incompatible materials.
