Quality Control

Our 2,6,10-Trimethylundeca-5,9-Dienal is produced under strict quality management systems to ensure batch-to-batch consistency and high purity. Each lot undergoes rigorous analytical testing, including gas chromatography (GC) and infrared spectroscopy (IR), to verify identity, purity, and olfactory profile. A comprehensive Certificate of Analysis (COA) detailing all specifications is provided with every shipment to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at temperatures between 15-25°C (59-77°F). Due to its properties of being easily oxidized, it is recommended to store under an inert atmosphere (e.g., nitrogen) for long-term preservation. Keep away from heat, sparks, and open flames.
