Quality Control

Our 2-Cyclobuten-1-One is produced and tested under strict quality management protocols to ensure batch-to-batch consistency and high purity. We provide comprehensive analytical data, including HPLC/GC purity and identity confirmation (IR, NMR). A detailed Certificate of Analysis (COA) is supplied with each shipment, and custom purity grades or analytical packages are available to meet specific project requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, well-ventilated area at recommended room temperature (15-25°C). Due to its highly volatile and light-sensitive nature, containers should be kept sealed and away from heat sources and open flame. Use under an inert atmosphere for extended storage to maintain optimal purity.
