Quality Control

Every batch of 2,5-Bis-(4-Aminophenyl)Pyridine is manufactured under a strict quality management system. Our products undergo rigorous quality testing, including chromatographic purity analysis and identity confirmation, to ensure compliance with exacting customer and industry standards. Comprehensive Certificates of Analysis (COA) detailing purity, assay, and impurity profiles are available upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated place at a controlled room temperature (15-25°C). Due to its sensitivity to oxidation, it is recommended to store under an inert atmosphere (e.g., nitrogen or argon) for long-term preservation. Keep away from strong oxidizing agents.
