Quality Control

Our 2-Oxocyclopentanecarboxylic Acid Hexyl Ester is produced under a strict quality management system. Each batch undergoes comprehensive analytical testing, including chromatographic purity analysis and identity confirmation, to ensure it meets precise customer specifications and industry standards. A Certificate of Analysis (COA) detailing purity, physical properties, and test results is provided with every shipment to guarantee traceability and batch-to-batch consistency.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, well-ventilated area away from heat sources and incompatible materials. Due to its highly volatile nature, ensure containers are kept tightly sealed when not in use to prevent evaporation and concentration changes. Recommended storage temperature is 2-8°C for extended stability, though short-term storage at 15-25°C is acceptable.
