Quality Control

Our 4-(Pyridin-4-Ylethynyl)-1-Naphthoic Acid is produced under strict quality management protocols. Each batch undergoes comprehensive analytical testing, including HPLC for purity assessment and NMR/IR for structural confirmation, to ensure it meets the high standards required for research and development applications. A Certificate of Analysis (COA) detailing batch-specific results is provided with every shipment to guarantee traceability and consistency.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at a controlled room temperature (15-25°C). Due to its hygroscopic nature, the container must be kept tightly sealed after opening to minimize exposure to atmospheric moisture. For long-term storage, consider using desiccants.
