Quality Control

Every batch of 4-Methyl-5-(Oxiran-2-Yl)Isobenzofuran-1(3H)-One is manufactured and tested under a strict quality management system. We provide comprehensive analytical data to ensure the material meets the high-purity standards required for research and scale-up activities. A detailed Certificate of Analysis (COA), including results for identity, purity, and impurity profiles (typically by HPLC, GC, NMR, and IR), is supplied with each shipment to guarantee traceability and consistency.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at a controlled room temperature (typically 15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent degradation. Keep away from heat, sparks, and open flame.
