Quality Control

Our Heptadecanal is produced under a strict quality management system. Every batch undergoes comprehensive analytical testing, including GC, HPLC, and IR spectroscopy, to ensure identity, purity, and consistency. A Certificate of Analysis (COA) detailing all test results is provided with each shipment to guarantee compliance with your specifications and industry standards.

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 sensitivity to oxidation, it is recommended to store under an inert atmosphere (e.g., nitrogen) for long-term preservation. Keep away from strong oxidizing agents and heat sources.
