Quality Control

Our L-Isoserine is manufactured under a strict quality management system. Every batch undergoes comprehensive analytical testing, including HPLC for purity and chiral integrity, to ensure it meets the high standards required for research and commercial synthesis. Certificates of Analysis (COA) detailing identity, purity, and impurity profiles are provided and can be tailored to meet specific customer or regulatory requirements, including those for cGMP applications.

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 each use to prevent absorption of atmospheric moisture, which can affect stability and handling properties.
