Quality Control

Our cis-2,4-Dimethyloxetane is manufactured under strict quality control protocols to ensure batch-to-batch consistency and high purity. Each lot is analyzed using advanced chromatographic and spectroscopic techniques (GC, GC-MS, NMR) to verify identity and assay. A comprehensive Certificate of Analysis (COA) detailing purity, physical properties, and impurity profiles is provided with every shipment, ensuring full traceability and compliance with your research or production requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, well-ventilated area away from heat sources and incompatible materials such as strong acids and oxidizing agents. Due to its highly volatile nature, containers must be kept tightly sealed when not in use. Recommended storage temperature is 2-8°C for long-term stability.
