Quality Control

Our 3,5-Dimethylisoxazole-4-Carbonyl Chloride is manufactured under strict quality management systems to ensure batch-to-batch consistency and high purity suitable for research and industrial synthesis. Each lot is accompanied by a comprehensive Certificate of Analysis (COA) detailing purity, identity, and impurity profiles. We adhere to relevant industry standards and can provide material tailored to specific project requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place. 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. Recommended storage temperature is 2-8°C for long-term stability.
