Quality Control

Our trans-4-Methyl-2-Pentene is manufactured under strict quality management systems to ensure batch-to-batch consistency and high purity. Each lot is subjected to comprehensive analytical testing, including GC, NMR, and IR spectroscopy, to verify identity, purity, and the absence of critical impurities. A Certificate of Analysis (COA) detailing all specifications is provided with every shipment to support your quality assurance protocols.

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 when not in use to prevent evaporation and concentration changes. Recommended storage temperature is 2-8°C (refrigerated) for long-term stability.
