Quality Control

Our n-Ethyl-n-(2-Hydroxyethyl)-p-Phenylenediamine Sulfate Monohydrate is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing to ensure it meets precise specifications for identity, purity, and composition. Certificates of Analysis (COA) documenting these results are available upon request to support your quality assurance and regulatory compliance needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). This material is light-sensitive (store away from light) and easily oxidized (store under inert atmosphere); prolonged exposure to air and light should be avoided to maintain stability and efficacy.
