Quality Control

Our 1-Heptyne is produced and handled under strict quality management protocols to ensure batch-to-batch consistency and high purity. Each lot undergoes comprehensive analysis, including gas chromatography (GC) for purity and identity confirmation. A detailed Certificate of Analysis (COA) is provided with every shipment, documenting all critical quality parameters to support your research and development needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, well-ventilated place away from heat, sparks, and open flames. Due to its highly volatile nature, keep the container tightly sealed when not in use. Recommended storage temperature is 2-8°C to minimize evaporation and maintain stability.
