Quality Control

Every batch of our Melengestrol Acetate-D3 Solution is manufactured and analyzed under strict quality systems. We guarantee high chemical and isotopic purity, with comprehensive characterization using NMR, HRMS, and HPLC. A detailed Certificate of Analysis (COA) is provided for each lot, confirming identity, concentration (ppm), isotopic enrichment, solvent composition, and purity. Our quality commitment supports GMP/GLP-compliant laboratory workflows.

Storage

Preserve in a tightly closed container, protected from light. Store at 2-8°C (refrigerated). Due to the highly volatile nature of the solvent, ensure containers are securely sealed and stored upright in a well-ventilated area. For long-term stability, consider storage at -20°C.
