Quality Control

Our Oxybis(Methyleneoxymethylene) Bis(1,3-Dihydro-1,3-Dioxoisobenzofuran-5-Carboxylate) is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC for purity and identity confirmation via FT-IR and NMR, to ensure it meets exacting standards for research and industrial use. A comprehensive Certificate of Analysis (COA) detailing purity, impurities, and physical characteristics is provided with every shipment to guarantee traceability and consistency.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at a controlled room temperature (15-25°C). Keep away from heat, sparks, and open flame. Due to the potential for hydrolysis of ester functionalities, the container must be kept tightly sealed in a low-humidity environment.
