Quality Control

Our production of 2-Isoxazolidinecarbonyl Chloride, 3-Oxo- (9Ci) adheres to stringent quality management protocols to ensure batch-to-batch consistency and reliability. Each lot undergoes comprehensive analytical testing, including purity assay and impurity profiling, to meet exacting customer specifications. A Certificate of Analysis (COA) detailing all test results is provided with every shipment, ensuring full traceability and compliance with your quality assurance requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (typically 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.
