Quality Control

Our Mpeg3-Ch2Ch2Cooh is manufactured under a strict quality management system. Each batch undergoes rigorous analytical testing, including HPLC for purity and assay, NMR for structural confirmation, and titration for acid value determination, to ensure it meets the high standards required for research and cGMP manufacturing. Certificates of Analysis (COA) with detailed specifications and chromatograms are provided for every shipment.

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 can affect product stability and performance.
