Quality Control

Our 1-Ethyl-2-Methylcyclohexane is produced and handled under a strict quality management system. Each batch undergoes comprehensive analytical testing, including Gas Chromatography (GC) for purity and identity verification, to ensure it meets exacting specifications for industrial and research use. A Certificate of Analysis (COA) detailing all 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, sparks, and open flames. Due to its highly volatile nature, containers must be kept tightly sealed when not in use to prevent evaporation and maintain purity. Recommended storage temperature is 2-25°C.
