Quality Control

Our 2-Octynoic Acid cis-3-Hexen-1-Yl Ester is produced under strict quality management protocols. Every batch undergoes comprehensive analytical testing, including chromatographic purity analysis and identity confirmation, to ensure it meets the high standards required for fine chemical and fragrance applications. A Certificate of Analysis (COA) detailing specific results for purity, identity, and other critical parameters is provided with each shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, well-ventilated area at controlled room temperature (15-25°C). This compound is easily oxidized; for long-term storage, maintaining an inert atmosphere (e.g., under nitrogen) is recommended to preserve stability and purity. Keep away from heat, sparks, and open flame.
