Quality Control

Our production of 2,5,8,11,14,17-Hexaoxanonadecan-19-Ol, Methanesulfonate adheres to stringent quality management protocols. Every batch undergoes comprehensive analytical testing, including HPLC for purity and identity confirmation, to ensure it meets precise customer specifications. Certificates of Analysis (COA) documenting all critical parameters are available upon request, providing full traceability and quality assurance for your R&D and manufacturing processes.

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 under an inert atmosphere (e.g., nitrogen or argon) after initial opening to prevent degradation.
