Quality Control

Our 4-Methoxy-o-Phenylenediamine Dihydrochloride is manufactured under a strict quality management system. Each batch undergoes comprehensive analytical testing, including HPLC for purity and identity confirmation via IR and NMR spectroscopy, to ensure it meets stringent specifications for use in sensitive applications. Certificates of Analysis (COA) documenting all test results are available upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). Due to its hygroscopic nature, the container must be kept tightly sealed to prevent moisture absorption, which can affect product stability and performance.
