Quality Control

Our 3-Isoxazolemethanol, Alpha,5-Dimethyl-, (S)- (9Ci) is produced under strict quality management protocols. Each batch undergoes comprehensive analytical testing, including chiral purity analysis by HPLC, to ensure it meets the exacting standards required for advanced synthetic applications. A Certificate of Analysis (COA) detailing identity, purity (typically >98%), enantiomeric excess (ee), and impurity profile is provided with every shipment to guarantee traceability and 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 after opening to prevent moisture absorption, which may affect stability and handling properties.
