Quality Control

Our Bis[(R)-[Cyano(Phenyl)Methyl]Ammonium] [R-(R*,R*)]-Tartrate is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing to ensure compliance with high-purity standards suitable for research and synthesis applications. Certificates of Analysis (COA) detailing purity, chiral purity (enantiomeric excess), and impurity profiles are available upon request.

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 nature, the container must be kept tightly sealed to minimize exposure to atmospheric moisture. Keep away from incompatible materials.
