Quality Control

Our 2-[(Ethylamino)Methyl]-4-Aminophenol-D5 Dihydrochloride is manufactured under strict quality systems to ensure the high chemical purity and isotopic enrichment required for analytical applications. Each batch is accompanied by a comprehensive Certificate of Analysis (COA) detailing purity, isotopic purity (D-content), and identity confirmation via spectroscopic methods. We adhere to cGMP principles where applicable to support its use in regulated environments.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at a controlled room temperature (15-25°C). Due to its hygroscopic nature, the container should be kept in a desiccated environment to prevent moisture absorption, which can affect stability and purity. For long-term storage, consider storing under an inert atmosphere.
