Quality Control

Our trans-3-Methyl-2-Pentene is produced and handled under strict quality management protocols to ensure batch-to-batch consistency and high purity. Each lot undergoes comprehensive analytical testing, including GC, GC-MS, and NMR, to verify identity, purity, and the absence of critical impurities. A Certificate of Analysis (COA) detailing all test results is provided with every shipment to support your quality assurance processes.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, well-ventilated area away from heat, sparks, and open flame. Due to its highly volatile and easily oxidized nature, it is recommended to store under an inert atmosphere (e.g., nitrogen) for long-term stability. Keep container tightly sealed when not in use to prevent evaporation and contamination.
