Quality Control

Our 5-Phenyl-3-tert-Butylisoxazole is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC, GC, and NMR, to ensure high purity and consistency. Certificates of Analysis (COA) documenting identity, purity, and impurity profiles are available for every shipment. We are committed to meeting the quality standards required for research and industrial-scale applications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed to prevent degradation from atmospheric moisture.
