Quality Control

Our Rocastine is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing, including HPLC, NMR, and MS, to ensure identity, purity, and consistency. We provide full traceability and Certificates of Analysis (COA) that detail all specifications and test results. Our quality commitment aligns with cGMP principles for pharmaceutical intermediates, ensuring reliability for your most critical applications.

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 hygroscopic nature, the container must be kept tightly sealed to minimize exposure to atmospheric moisture. For long-term storage, consider the use of desiccants.
