Quality Control

Our Cefoselis Hydrochloride is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing, including HPLC for purity, identification by IR and NMR spectroscopy, and tests for residual solvents and related substances, ensuring it meets high-grade standards suitable for pharmaceutical research. Certificates of Analysis (COA) with detailed specifications are provided for every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed in a dry environment to prevent degradation. For long-term storage, consider desiccants or inert atmosphere conditions.
