Quality Control

Our 3-Hepten-5-Yn-2-One, 3-Methyl-, (3Z)- (9Ci) is produced under strict quality management protocols. Each batch undergoes rigorous analytical testing, including chromatography and spectroscopy, to ensure high purity and consistency. Certificates of Analysis (COA) detailing purity, identity, and impurity profiles are provided with every shipment to support your quality assurance and regulatory needs.

Storage

Preserve in a tightly closed container, protected from light. Store under an inert atmosphere (e.g., nitrogen or argon) at controlled room temperature (15-25°C) in a cool, dry, and well-ventilated area. Keep away from heat, sparks, and open flame. Due to its light-sensitive and easily oxidized nature, minimize exposure to air and light during handling.
