Quality Control

Our L-Valine, n-[(4-Methoxyphenyl)Sulfonyl]- is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing, including chiral purity verification, to ensure it meets the high standards required for research and synthesis. A detailed Certificate of Analysis (COA) is provided with every shipment, documenting key parameters such as assay, enantiomeric excess, and impurity profiles.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place 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 degradation from atmospheric moisture.
