Quality Control

Our 4-Isoxazolecarbonyl Chloride, 5-(2-Furyl)-3-Methyl- (7Ci) is produced under strict quality management protocols. Each batch undergoes rigorous analytical testing, including HPLC, NMR, and IR spectroscopy, to ensure identity, purity, and consistency. Certificates of Analysis (COA) documenting all specifications are available upon request, supporting your quality assurance and regulatory needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, 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 decomposition. Keep away from strong acids and incompatible materials.
