Quality Control

Our Ethyl 4-Hydroxy-2-Methyl-5-Oxotetrahydrofuran-3-Carboxylate is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC, GC, and NMR, to ensure identity, purity, and consistency. Certificates of Analysis (COA) detailing all specifications are provided with every shipment. We can support development projects with custom purity grades, including research and pharmaceutical intermediate standards.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at a controlled room temperature (15-25°C). Due to its hygroscopic nature, the container must be kept tightly sealed after opening to prevent moisture absorption, which may affect stability and performance. Keep away from incompatible materials.
