Quality Control

Our 1-Hepten-3-Yne is produced and handled under strict quality management protocols to ensure batch-to-batch consistency and reliability for your critical processes. Each lot undergoes comprehensive analytical testing, including purity assay and impurity profiling by GC and GC-MS. A Certificate of Analysis (COA) detailing all specifications is provided with every shipment to support your quality assurance and regulatory compliance needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated place at room temperature (15-25°C). Keep away from heat, sparks, and open flames. Due to its unsaturated nature, it is recommended to store under an inert atmosphere (e.g., nitrogen or argon) for long-term stability and to minimize the risk of polymerization or oxidation.
