Quality Control

Our 2,3-Dimethyl-1-Butene is produced and handled under stringent quality management protocols to ensure batch-to-batch consistency and high purity. Each lot is analyzed using advanced chromatographic and spectroscopic techniques (GC, GC-MS, NMR) to verify identity, purity, and the absence of critical impurities. A comprehensive Certificate of Analysis (COA) detailing all test results is provided with every shipment, ensuring full traceability and compliance with customer specifications.

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 away from strong oxidizing agents. Recommended storage temperature: 2-8°C (refrigerated) for optimal shelf life.
