Quality Control

Our cis-3-Penten-1-yne is produced under stringent quality management systems. Every batch undergoes rigorous analytical testing, including GC, GC-MS, and NMR, to ensure high chemical purity and identity confirmation. A comprehensive Certificate of Analysis (COA) detailing purity, assay, and impurity profiles is provided with each shipment to guarantee traceability and compliance with your research or production specifications.

Storage

Preserve in a tightly closed container, protected from light. Due to its highly volatile nature, store in a cool, well-ventilated place, preferably at 2-8°C (refrigerated) or as specified on the label. Keep away from heat, sparks, open flames, and oxidizing agents. Containers should be kept tightly sealed when not in use to prevent evaporation and potential concentration of peroxides.
