Quality Control

Our 2,2,5,5-Tetramethyl-3-Hexyne is produced under strict quality management protocols to ensure batch-to-batch consistency and high purity for research and development applications. We provide comprehensive analytical data, including Gas Chromatography (GC) and Nuclear Magnetic Resonance (NMR) spectroscopy, to verify identity and purity. A Certificate of Analysis (COA) is available for every batch upon request.

Storage

Preserve in a tightly closed container, protected from light. Due to its highly volatile nature, store in a cool, well-ventilated place, away from heat and ignition sources. Recommended storage temperature is 2-8°C (refrigerated) for long-term stability. Keep container tightly sealed when not in use to prevent evaporation and potential concentration changes.
