Quality Control

Our (S)-(-)-4-Isobutyloxazolidine-2,5-Dione is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing to ensure high chemical and chiral purity, meeting the stringent requirements for advanced synthetic applications. A comprehensive Certificate of Analysis (COA) detailing purity, enantiomeric excess, and impurity profiles is provided with every shipment to guarantee traceability and batch-to-batch consistency.

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 nature, the container must be kept tightly sealed to prevent moisture absorption, which can affect stability and performance. Keep away from incompatible materials.
