Quality Control

Our 4,4',6,6'-Tetranitrodiphenic Acid is manufactured under strict process controls to ensure batch-to-batch consistency and high purity. Each lot is subjected to comprehensive analytical testing, including HPLC for assay and purity determination. A Certificate of Analysis (COA) detailing all test results is provided with every shipment to guarantee compliance with your technical requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area away from heat, sparks, and open flames. Due to its oxidizable nature, long-term storage under an inert atmosphere (e.g., nitrogen or argon) is recommended to maintain product integrity. Keep away from incompatible materials such as strong reducing agents.
