Quality Control

Our All-trans-3-Hydroxyretinal is produced under stringent quality management systems. Each batch undergoes comprehensive analytical testing, including HPLC for purity and identity confirmation via spectroscopic methods, to ensure it meets the high standards required for research and development. Certificates of Analysis (COA) detailing all specifications are available upon request.

Storage

Preserve in a tightly closed container, protected from light. Store under an inert atmosphere (e.g., nitrogen or argon) at recommended cold chain conditions (typically -20°C or below) to prevent oxidation and ensure long-term stability. Allow the container to reach room temperature in a desiccator before opening to minimize moisture uptake.
