Quality Control

Our 3-Methoxy-o-Phenylenediamine Hydrochloride is manufactured under strict quality management systems to ensure batch-to-batch consistency and high purity. Each lot undergoes comprehensive analytical testing, including HPLC for assay and impurity profiling. A Certificate of Analysis (COA) detailing all test results is provided with every shipment, confirming compliance with agreed specifications. We support cGMP and ISO standards for pharmaceutical and industrial intermediates.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after opening to prevent degradation from atmospheric moisture. Keep away from heat, sparks, and open flame.
