Quality Control

Our Guanylurea Phosphate is manufactured under a strict quality management system. Each batch undergoes comprehensive analytical testing to ensure consistent purity, identity, and performance. A Certificate of Analysis (COA) detailing key parameters such as assay, moisture content, and solubility is provided with every shipment to guarantee compliance with your technical requirements.

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 sealed to prevent absorption of atmospheric moisture, which can affect product quality.
