Quality Control

Our 4-Hexen-2-One, 3-Methyl-, [R-(E)]- (9Ci) is produced under strict quality management systems. Each batch undergoes comprehensive analytical testing, including chiral purity analysis by GC or HPLC, to ensure high chemical and enantiomeric purity suitable for demanding synthetic applications. Certificates of Analysis (COA) with detailed specifications are provided to guarantee traceability and batch-to-batch consistency.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, well-ventilated place, away from heat and ignition sources. Due to its highly volatile and easily oxidized nature, it is recommended to store under an inert atmosphere (e.g., nitrogen or argon) for long-term stability. Recommended storage temperature is 2-8°C.
