Quality Control

Our 2-Methyl-1-Butene is produced and handled under stringent quality management protocols 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 requirements. A Certificate of Analysis (COA) detailing all test results is provided with every shipment, ensuring full traceability and compliance with relevant industry standards.

Storage

Preserve in a tightly closed container, protected from light. Due to its highly volatile nature, store in a cool, well-ventilated area away from heat, sparks, and open flames. Recommended storage temperature is between 2°C and 8°C (36°F and 46°F) to minimize evaporation and maintain stability. Keep away from strong oxidizing agents. Containers should be kept upright and securely sealed when not in use.
