Quality Control

Our 4-Methylheptane is produced and handled under a stringent quality management system. Each batch undergoes comprehensive analytical testing, including gas chromatography (GC) for purity and identity confirmation, to ensure it meets precise customer specifications. Certificates of Analysis (COA) detailing all relevant parameters are provided to guarantee traceability and batch-to-batch consistency for your critical applications.

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, keep container tightly sealed when not in use to prevent evaporation and maintain purity. Recommended storage temperature is between 15°C and 25°C.
