Quality Control

Every batch of our 25-Ethoxy-27-Diethoxyphosphoryloxycalix[4]Arene is produced and tested under a strict quality management system. We employ advanced analytical techniques including NMR, HPLC, and MS to ensure identity, purity, and consistency. A comprehensive Certificate of Analysis (COA) detailing all specifications is provided with each shipment to support your quality assurance and regulatory needs.

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 opening to prevent degradation from atmospheric moisture. Keep away from incompatible materials.
