Quality Control

Every batch of Rx-518 undergoes rigorous quality testing to ensure compliance with stringent industry standards. Our quality management system is designed to guarantee batch-to-batch consistency, purity, and identity. Certificates of Analysis (COA) detailing specific test results are available upon request to support your quality assurance and regulatory documentation 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 (typically 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. Keep away from incompatible materials.
