Quality Control

Our Dl-Threo-3-Phenylserine Hydrate is manufactured under a strict quality management system. Every batch undergoes comprehensive analytical testing, including HPLC for purity, chiral analysis, and identity confirmation, to ensure it meets the specified 98% purity grade. A detailed Certificate of Analysis (COA) is provided with each shipment, documenting all critical quality attributes. Our quality commitment supports applications requiring reliable and consistent material for research and scale-up activities.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after opening to prevent absorption of atmospheric moisture, which may affect purity and handling properties.
