Quality Control

Our 5-Methyl-3-heptyne is produced under strict quality management protocols to ensure batch-to-batch consistency and high purity. Each lot undergoes comprehensive analytical testing, including gas chromatography (GC) and spectroscopic analysis, to verify identity and purity. A detailed Certificate of Analysis (COA) is provided with every shipment, documenting all relevant specifications. We adhere to cGMP principles where applicable to support our customers in regulated industries.

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, sparks, and open flames. Recommended storage temperature is between 2°C and 8°C (refrigerated) to minimize degradation and maintain stability. Keep container tightly sealed when not in use to prevent evaporation and potential contamination.
