Quality Control

Every batch of m-Phenylenediamine, 4-Isopropyl-, Hydrate (5Ci) is produced and tested under a strict quality management system. We ensure compliance with relevant industry standards for fine chemical intermediates. Comprehensive testing includes identity confirmation, purity assay, and control of key impurities. A Certificate of Analysis (COA) detailing all test results is provided with each shipment to guarantee traceability and batch-to-batch consistency for your critical processes.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated place at a controlled room temperature (15-25°C). Due to its hygroscopic and easily oxidized nature, the container must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) after opening to minimize moisture uptake and oxidative degradation. Keep away from strong oxidizing agents.
