Quality Control

Our 5-Methyl-5-Hexen-2-One is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing, including GC, HPLC, and NMR, to ensure identity, purity, and consistency. We provide detailed Certificates of Analysis (COA) with every shipment, confirming compliance with agreed specifications. Our quality commitment supports applications in regulated industries, including fragrance and pharmaceutical intermediates.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, well-ventilated area away from heat sources and incompatible materials such as strong acids, bases, and oxidizing agents. Due to its highly volatile nature, keep containers tightly sealed when not in use. Recommended storage temperature is 2-8°C for extended stability, though short-term storage at controlled room temperature (15-25°C) is acceptable.
