Quality Control

Our Leucine, n-(1-Oxobutyl)- is produced under a strict quality management system. Each batch undergoes comprehensive analytical testing, including chiral purity and impurity profile analysis by HPLC, to ensure it meets the high standards required for research and synthesis. Certificates of Analysis (COA) detailing purity, enantiomeric excess, and other critical parameters are available upon request.

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.
