Quality Control

Our 2,8,8-Trimethylnonane-2,7-Diol is manufactured under a strict quality management system. Each batch undergoes rigorous analytical testing, including assay, identity confirmation, and impurity profiling, to ensure it meets precise customer specifications and industry standards. A comprehensive Certificate of Analysis (COA) documenting purity, physical properties, and test results is provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). Due to its hygroscopic nature, the container must be kept tightly sealed to prevent moisture absorption, which can affect product quality. Keep away from strong oxidizing agents.
