Quality Control

Our 1,11-Undecanediol is manufactured under a strict quality management system. Each batch undergoes comprehensive analytical testing, including assay, identity confirmation, and impurity profiling, to ensure it meets precise specifications. Certificates of Analysis (COA) are provided with every shipment to guarantee traceability and batch-to-batch consistency for your critical 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 nature, the container must be kept tightly sealed to prevent moisture absorption, which can affect product quality. Keep away from strong oxidizing agents.
