Quality Control

Our Rhodopsin 18 Methyl Ester is produced under strict quality management protocols. Each batch undergoes comprehensive analytical testing, including HPLC for purity and identity confirmation via spectroscopic methods (NMR, IR), to ensure it meets the stringent requirements of research and development applications. A Certificate of Analysis (COA) detailing all specifications is provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. For long-term stability, store at -20°C or below under an inert atmosphere (argon or nitrogen). Allow the container to reach room temperature in a dark environment before opening to prevent condensation. Keep away from strong oxidizers.
