Diammonium hydrogen phosphite CAS 51503-61-8

Diammonium hydrogen phosphite CAS 51503-61-8

Application Scenarios:

Agricultural Grade:

1. Novel Disease Resistance Inducer (“Integrated Fertilizer and Pesticide”): * The phosphate ions in diammonium hydrogen phosphate have extremely strong systemic conductivity. After spraying, it can be rapidly absorbed by the xylem and phloem of crops.

2. High-Efficiency Foliar Fertilizer and Root Promoter: It can be used as a fertilizer to control shoot growth, promote flowering, fruit enlargement, and ripening in the mid-to-late stages of crop growth, while also stimulating root development.

Industrial Grade:

1. Metal Surface Treatment and Chemical Plating (Complexing Reducing Agent): In the chemical nickel plating and electroplating processes of precision electronic components and automotive parts, it acts as a reducing agent and stabilizer. It can precisely control the deposition rate of metal ions, resulting in a plating layer with higher hardness, wear resistance, and uniform thickness.

2. Polymer Material Stabilizer: In the production of plastics such as nylon, polyvinyl chloride (PVC), and polycarbonate (PC), as well as synthetic fibers, it acts as a heat stabilizer and antioxidant. It can effectively intercept the degradation of materials caused by heat and oxygen during high-temperature processing, preventing yellowing and brittleness of products.

3. Nylon Brightener: Used in the textile industry as a chemical brightening agent for synthetic fibers such as nylon.

Food Grade:

1. Specific Nutrients (Phosphorus and Nitrogen Sources) in Fermentation Industry: Serves as a high-purity source of complex trace elements for microorganisms in industrial food fermentation, enzyme production, antibiotic fermentation, or the cultivation of special yeasts (providing both highly active nitrogen and phosphorus). It acts as a fermentation buffer, stabilizing the system's pH value, and is completely removed during subsequent product extraction and washing processes.

2. Food-Grade Boiler Water and Industrial Steam Network Maintenance: Scale and corrosion inhibitors are required in steam boiler water used for heating food or sterilizing equipment in dairy, meat processing, and food canning plants. To prevent accidental steam leakage and trace contamination of food, food-grade diammonium hydrogen phosphate, with strictly limited heavy metal content, must be used for water treatment.
