Quality Control

Our 3-(2,6-Dichlorophenyl)-5-Methylisoxazole-4-Carbonyl Chloride is manufactured under strict quality management systems. Every batch undergoes rigorous analytical testing, including HPLC, NMR, and IR spectroscopy, to ensure identity, purity, and consistency. Certificates of Analysis (COA) detailing all specifications are provided with each shipment to guarantee compliance with your research or production requirements.

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 (moisture-sensitive) nature, the container must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent degradation. Keep away from strong acids and incompatible materials.
