Quality Control

Every batch of Valine, n-(2-Aminoethyl)- is produced under a strict quality management system. We employ advanced analytical techniques, including HPLC, NMR, and chiral analysis, to ensure identity, purity, and enantiomeric excess meet exacting standards. A comprehensive Certificate of Analysis (COA) detailing purity, assay, and impurity profiles is provided with each shipment to support your quality and regulatory requirements.

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.
