Quality Control

Every batch of (5-Methylisoxazol-3-Yl)Methanol is produced and tested under strict quality management systems. We ensure compliance with relevant industry standards for fine chemical intermediates. Comprehensive analytical testing, including HPLC, GC, and NMR, is performed to guarantee identity, purity, and consistency. Certificates of Analysis (COA) are provided with each shipment and are available upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after opening to prevent degradation from atmospheric moisture. Keep away from incompatible materials.
