Description

Ammophos CAS NO 12735-97-6 is a high-purity, commercially significant ammonium phosphate fertilizer compound. This product is valued for its dual nutrient content, providing a readily available source of both nitrogen and phosphorus for plant growth. It is essential for manufacturers in the agricultural sector seeking to formulate efficient, water-soluble fertilizers for a variety of crops. Its consistent quality ensures reliable performance in both direct application and as a key ingredient in complex fertilizer blends.

Application

• High-Efficiency Fertilizer Production: A primary raw material for manufacturing water-soluble NP fertilizers, including MAP (Monoammonium Phosphate) and DAP (Diammonium Phosphate) grades.
• Hydroponics and Fertigation Systems: Used in nutrient solutions for soilless cultivation and irrigation systems due to its excellent solubility and balanced nutrient profile.
• Specialty Agricultural Formulations: Incorporated into foliar sprays, starter fertilizers, and greenhouse feeding programs to promote vigorous early plant development.
• Industrial Process Chemical: Serves as a flame retardant additive in certain materials and as a nutrient source in controlled fermentation processes.
• Feed Supplement: Used in the production of mineral feed phosphates for animal nutrition after further processing and purification to meet relevant standards.

Quality Control

Our Ammophos is manufactured under strict quality management protocols to ensure batch-to-batch consistency and compliance with international fertilizer and chemical standards. Each lot is analyzed for critical parameters including nutrient content (N and P2O5), heavy metals, and moisture. A comprehensive Certificate of Analysis (COA) detailing purity, assay, and impurity profiles is provided with every shipment to guarantee product integrity for your processes.

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). This material is hygroscopic (moisture-sensitive) and must be kept in original, sealed packaging or moisture-proof containers to prevent caking and degradation. Keep away from incompatible materials such as strong alkalis.
