Quality Control

Our Dl-β-Phenylserine Threo Form is manufactured under a strict quality management system. Each batch undergoes comprehensive analytical testing, including HPLC for purity and chiral analysis, to ensure it meets exacting standards for research and industrial use. A Certificate of Analysis (COA) detailing identity, purity, and specific impurity profiles is provided with every shipment.

Storage

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