Quality Control

Our 1-Naphthyl Phosphate Disodium Salt Monohydrate is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC for purity and identity confirmation, to ensure it meets the high standards required for diagnostic and research applications. Certificates of Analysis (COA) with detailed specifications are provided for every shipment to guarantee traceability and performance consistency.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after each use to prevent absorption of atmospheric moisture, which can affect product stability and performance.
