Quality Control

Our Hydrochloride CAS NO 243961-05-9 is manufactured under a strict quality management system. Each batch undergoes rigorous analytical testing to ensure it meets high-purity standards suitable for research and synthesis applications. We provide comprehensive Certificates of Analysis (COA) with detailed chromatographic and spectroscopic data, including HPLC purity, identity confirmation (IR, NMR), and impurity profile, upon request to support your quality assurance protocols.

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 to prevent exposure to atmospheric moisture, which can compromise product integrity. For long-term storage, consider using desiccants.
