Quality Control

Our 1,1'-Oxybis(2,2-Dimethoxy)Ethane is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing to ensure identity, purity, and consistency. We provide Certificates of Analysis (COA) with key parameters including assay (by GC or HPLC), identity confirmation (by IR or NMR), and impurity profile. Our quality commitment aligns with cGMP principles for pharmaceutical intermediates, ensuring reliability for your critical processes.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). Due to its properties of being easily oxidized and highly volatile, it is recommended to store under an inert atmosphere (e.g., nitrogen or argon) for long-term stability and to minimize headspace in opened containers. Keep away from heat, sparks, and open flame.
