Quality Control

Our production of 4,7,10,13,16-Pentamethyl-2,5,8,11,14,17-Hexaoxahenicosan-19-Ol adheres to a stringent quality management system. Every batch undergoes rigorous analytical testing, including HPLC for purity, GC for residual solvents, and titration for hydroxyl value, to ensure consistency and compliance with customer specifications. A comprehensive Certificate of Analysis (COA) detailing all test results is provided with each shipment to guarantee traceability and quality assurance for your B2B applications.

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 initial opening to prevent absorption of atmospheric moisture, which can affect product quality. Keep away from incompatible materials such as strong oxidizing agents.
