Quality Control

Our Isoxazole, 3-Isocyanato-5-Propyl- (9Ci) is produced under stringent quality management systems. Each batch undergoes rigorous analytical testing, including chromatographic purity analysis and identity confirmation, to ensure it meets the high standards required for research and industrial synthesis. Certificates of Analysis (COA) detailing specific batch results are available upon request to support your quality assurance and regulatory documentation.

Storage

Preserve in a tightly closed container, protected from light. Due to its highly volatile nature and reactivity, store in a cool, dry, and well-ventilated place at a controlled room temperature (15-25°C/59-77°F). Keep away from strong bases and incompatible materials such as alcohols, amines, and moisture to prevent polymerization or degradation.
