Quality Control

Our [S,(+)]-4-Heptyne-2-Ol is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including chiral purity analysis by HPLC, to ensure it meets the high standards required for research and process chemistry. Certificates of Analysis (COA) detailing identity, purity, and enantiomeric excess are provided with every shipment to guarantee traceability and consistency.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent degradation.
