Quality Control

Our 7-Cyano-2-Heptene-4,6-Diynoic Acid is produced under strict quality management protocols. Every batch undergoes rigorous analytical testing, including HPLC, NMR, and FTIR, to ensure identity, purity, and consistency. A comprehensive Certificate of Analysis (COA) detailing all specifications is provided with each shipment to support your quality assurance and regulatory needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated place at a controlled room temperature (typically 15-25°C). Due to its conjugated polyyne and acid structure, it is recommended to store under an inert atmosphere for long-term stability and to minimize potential degradation.
