Quality Control

Our 3-Methyl-1-Butene is produced and handled under stringent quality management protocols. Each batch undergoes comprehensive analytical testing, including gas chromatography (GC) for purity and identity confirmation, to ensure it meets exacting standards for research and industrial use. Certificates of Analysis (COA) detailing all test results 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, sparks, and open flame. Due to its highly volatile nature, containers must be kept tightly sealed and under appropriate pressure conditions. Recommended storage temperature is 2-8°C (36-46°F) to minimize evaporation and maintain stability.
