Quality Control

Our Thenyldiamine is manufactured under a strict quality management system to ensure batch-to-batch consistency and high purity. Each lot undergoes comprehensive analytical testing, including assay, impurity profiling, and identity confirmation. A Certificate of Analysis (COA) detailing all test results is provided with every shipment to support your quality assurance protocols 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). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed to prevent absorption of atmospheric moisture. Keep away from heat, sparks, and open flame.
