Quality Control

Our 2,18-Phosphomolybdic Acid Sodium Salt is manufactured under a rigorous quality management system. Each batch is tested to ensure it meets precise chemical and physical specifications relevant to its industrial and research applications. A comprehensive Certificate of Analysis (COA), detailing purity, assay, and impurity profiles, is provided with every shipment to guarantee traceability and performance consistency.

Storage

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