Quality Control

Our 3-Methyl-5-Isoxazoleacetic Acid 98 is manufactured under a strict quality management system. Every batch undergoes comprehensive analytical testing, including HPLC for purity, IR and NMR for structural confirmation, and tests for residual solvents and moisture, to ensure it meets the high standards required for research and industrial synthesis. A detailed Certificate of Analysis (COA) is provided with each shipment to guarantee traceability and compliance with your specifications.

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 after each use to prevent degradation from atmospheric moisture.
