Quality Control

Our 3,5-Diamino-4-Phenylazopyrazole is manufactured under a strict quality management system. Every batch undergoes comprehensive analytical testing, including HPLC for purity verification and spectroscopic methods for structural confirmation, to ensure it meets the high standards required for sensitive synthesis applications. We provide a detailed Certificate of Analysis (COA) with each shipment, documenting key parameters such as assay, impurity profile, and physical characteristics. Our quality commitment ensures batch-to-batch consistency and reliable performance for your critical processes.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at a controlled room temperature (typically 15-25°C). Keep away from heat, sparks, and open flame. Due to its light-sensitive nature, the container should be opaque or stored in darkness. For long-term storage, consider an inert atmosphere to maintain optimal stability.
