For professionals in the chemical and agricultural industries, a thorough understanding of product specifications is critical for informed purchasing decisions. Diammonium Hydrogen Phosphite (CAS 51503-61-8) is a compound with significant industrial and agricultural value, and knowing its precise properties ensures optimal application. As a leading supplier, we aim to provide clarity on the characteristics of this essential chemical.

Diammonium Hydrogen Phosphite, in its pure form, presents as a white crystal. This appearance is a key visual indicator of quality. Beyond its look, the chemical composition is defined by its molecular formula, (NH4)2HPO3•H2O, with a molecular weight of approximately 116.06 g/mol. A crucial specification for buyers is the assay, which for high-grade products, typically reaches ≥98.0%. This high purity is vital, particularly for its use in fertilizers, where consistent nutrient delivery is paramount, and also for its roles as a chemical intermediate.

Further technical specifications that buyers should consider include the nitrogen (N) and phosphorus pentoxide (P2O5) content, often listed as ≥20.4% and ≥51.9% respectively. The pH of a 5% solution, typically ranging from 7.4 to 7.7, indicates its slightly alkaline nature, which can be beneficial in certain soil applications. Moisture content is kept to a minimum, usually ≤2.0%, to ensure product stability and shelf life. Additionally, critical impurity levels, such as for Chlorine (Cl), Iron (Fe), Cadmium (Cd), Lead (Pb), and Arsenic (As), are rigorously controlled and should be well below stringent limits (e.g., Cl ≤0.0005%, Fe ≤0.0005%). Materials not soluble in water should also be minimal (≤0.01%).

We, as a manufacturer and supplier based in China, adhere to these specifications rigorously. Our production process is geared towards delivering Diammonium Hydrogen Phosphite that consistently meets these demanding criteria. When you are looking to buy this product, always cross-reference the supplier's Certificate of Analysis (COA) with your required specifications. We are happy to provide detailed COAs with each batch to ensure transparency and compliance.

Understanding these properties allows procurement specialists and R&D scientists to confidently integrate Diammonium Hydrogen Phosphite into their formulations and processes. Whether for enhancing agricultural outputs or for specialized industrial syntheses, sourcing from a reliable supplier that provides comprehensive technical data is essential. We encourage you to contact us for your Diammonium Hydrogen Phosphite needs, assured of quality and reliable information.
