Quality Control

Our Semotiadil (Racemate Fumarate) is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing, including HPLC for purity, identity confirmation by IR and NMR, and residual solvent analysis, to ensure it meets exacting standards for research and development use. A detailed Certificate of Analysis (COA) is provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at controlled room temperature (15-25°C). Due to its hygroscopic nature, the container must be kept tightly sealed in a dry environment to prevent moisture absorption.
