Quality Control

Our production of 2,4,6,8-Tetrakis(m-Toluidino)Pyrimido[5,4-D]Pyrimidine adheres to stringent quality management protocols to ensure batch-to-batch consistency and high purity. Each lot undergoes comprehensive analytical testing, including HPLC for purity, NMR and IR for structural confirmation, and tests for residual solvents and heavy metals. A Certificate of Analysis (COA) detailing all specifications is provided with every shipment, ensuring full traceability and compliance with your research or manufacturing requirements.

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). This compound is light-sensitive (store away from light) and easily oxidized (store under inert atmosphere); therefore, containers should be purged with an inert gas (e.g., nitrogen or argon) before sealing for long-term storage. Keep away from heat, sparks, and open flame.
