Quality Control

Our 4-Isoxazolecarboxylicacid,Hydrazide(9Ci) is produced under a strict quality management system to ensure batch-to-batch consistency and high purity for research and development applications. Each lot undergoes comprehensive analytical testing including HPLC for purity, NMR and IR for structural confirmation, and residual solvent analysis. A Certificate of Analysis (COA) detailing all specifications is provided with every shipment to guarantee compliance with your research protocols.

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 nature, the container must be kept tightly sealed after each use to minimize exposure to atmospheric moisture. For long-term storage, consider using desiccants.
