Quality Control

Our 5-Cyano-Dimethylisophthalate is manufactured under strict quality management systems to ensure batch-to-batch consistency and high purity. Each lot undergoes comprehensive analytical testing, including HPLC, GC, and NMR, to verify identity and purity against established specifications. A Certificate of Analysis (COA) detailing all test results is provided with every shipment. We support compliance with global regulatory frameworks, and custom purity grades (e.g., >98%, >99%) are available to meet specific project requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). Keep away from strong oxidizing agents, strong bases, and sources of ignition. For long-term storage, consider an inert atmosphere to maintain product integrity.
