Quality Control

Our 1,7-Diazaspiro[4.4]Nonane-2,6-Dione,(R)-(9Ci) is manufactured under a strict quality management system. Every batch undergoes comprehensive analytical testing to ensure identity, purity, and enantiomeric excess meet the highest standards for research and development use. Certificates of Analysis (COA) with detailed chromatographic and spectroscopic data are provided for full traceability and quality assurance.

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 may affect stability and handling properties.
