Quality Control

Our products undergo rigorous quality testing to ensure compliance with industry standards. Each batch is controlled via modern analytical techniques to guarantee identity, purity, and consistency. Certificates of Analysis (COA) detailing specific results for parameters such as assay (HPLC), related substances, and residual solvents are available upon request. We adhere to a quality management system to support our commitment to reliable supply for research and commercial scale applications.

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 after opening to prevent degradation from atmospheric moisture.
