Quality Control

Our 3,5-Di(Pyridine-4-Yl)Benzoic Acid is manufactured under a strict quality management system. Each batch undergoes comprehensive analytical testing, including HPLC for purity, NMR and IR for structural confirmation, and KF titration for moisture content, to ensure it meets the high standards required for research and development. Certificates of Analysis (COA) detailing all specifications are provided with every shipment and are available upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept sealed under an inert atmosphere (e.g., nitrogen or argon) for long-term storage to prevent degradation.
