Quality Control

Every batch of Xl 228 is manufactured and tested under a strict quality management system to ensure it meets the high standards required for research and industrial use. Our products undergo rigorous quality testing, including identity confirmation, purity assay, and impurity profiling, to ensure compliance with industry standards. Certificates of Analysis (COA) detailing all test results are available upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (typically 15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed and under dry conditions to prevent product degradation.
