Quality Control

Our Valine n-Acetyl-, -α--Ethyl- (4Ci) is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing, including HPLC for purity, chiral analysis for enantiomeric excess, and spectroscopic identification (NMR, IR, MS). We provide full traceability and Certificates of Analysis (COA) are available for all shipments, ensuring compliance with research and cGMP-grade material 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 in a dry environment to prevent product degradation. Keep away from incompatible materials.
