Quality Control

Our 4-Ethylcyclohexene is manufactured under strict quality management systems to ensure batch-to-batch consistency and high purity. Each lot undergoes comprehensive analytical testing, including gas chromatography (GC) for assay and impurity profiling, to meet exacting customer specifications. Certificates of Analysis (COA) documenting all critical quality attributes are provided with every shipment.

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 and easily oxidized nature, it is recommended to store under an inert atmosphere (e.g., nitrogen) for long-term preservation. Recommended storage temperature is 2-8°C.
