Quality Control

Our Ethanone, 1-(3,3-Dimethyloxiranyl)-, (+)- (9Ci) is produced and handled under a strict quality management system. Each batch is characterized and tested to ensure identity, purity, and enantiomeric excess meet the required specifications. Certificates of Analysis (COA) documenting physical properties, assay (by GC/HPLC), chiral purity, and impurity profiles are provided and available upon request. We support compliance with cGMP and ISO standards for pharmaceutical and industrial applications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at a controlled room temperature (typically 15-25°C). This compound is hygroscopic (moisture-sensitive); therefore, the container must be kept tightly sealed under an inert atmosphere (e.g., nitrogen) after opening to prevent degradation. Keep away from heat, sparks, and open flame.
