Quality Control

We supply Noradrenochrome in high-purity grades suitable for research and development. Every batch undergoes rigorous analytical testing, including HPLC for purity and identity confirmation via spectroscopic methods (IR, NMR). Our quality assurance process ensures consistency and reliability. A comprehensive Certificate of Analysis (COA) detailing purity, assay, and impurity profiles is provided with each shipment and is available upon request.

Storage

Preserve in a tightly closed container, protected from light. Store under an inert atmosphere (e.g., nitrogen or argon) at a controlled room temperature (15-25°C) to minimize oxidation and degradation. The container should be kept in a cool, dry, and well-ventilated area away from incompatible materials.
