Feature
1. High purity and strict impurity control: The product has high main content, and impurity indicators can be controlled according to different grades. For analytical reagents and high-precision applications, strict testing and control can be performed on chloride, sulfate, iron, sodium, and other trace impurities. Extremely low impurity content avoids interference in the preparation of laboratory buffer systems or precise analysis, ensuring the accuracy and reproducibility of test data; in food or specific formulation applications, strict impurity control also helps meet corresponding regulatory and safety standards.
2. Clear basic physicochemical information and reliable quality stability: The chemical formula is KH₂PO₄, CAS number 7778-77-0, and molecular weight is approximately 136.09 g/mol. The product is typically odorless, colorless crystals or white granules or crystalline powder, easily soluble in water and insoluble in ethanol. Its aqueous solution is acidic, with a pH range of 4.2 to 4.7 for a 1% solution, providing good buffering capacity and solution pH adjustment characteristics. It is stable in air, facilitating long-term storage and formulation applications, and effectively ensuring the stability of water-soluble fertilizers, nutrient solutions, and buffer systems.
3. Strong application functionality, one product for multiple uses across fields: As an inorganic salt providing both potassium and phosphorus, it is a high-quality water-soluble phosphorus-potassium fertilizer in agriculture, suitable for foliar or irrigation fertilization to promote plant growth. In food processing, it is listed by JECFA as food additive INS 340(i) and can serve as a buffering agent, neutralizing agent, sequestrant, and yeast nutrient. In laboratories and research, it is widely used for preparing buffer solutions, determining serum inorganic phosphorus and alkaline phosphatase activity, preparing bacterial culture media, and as a material for piezoelectric elements, electro-optical elements, and laser spectral wave generation. One product meets the needs of multiple industries.
4. Quality indicators precisely matched to intended use: Agricultural grade, food grade, industrial grade, and reagent grade standards are clearly distinguished. Agricultural grade focuses on phosphorus and potassium nutrients and water solubility; food grade meets food additive specifications; reagent grade follows ACS standards, covering content, pH, insoluble matter, loss on drying, heavy metals, and other detailed indicators. Customers can precisely select products based on actual processes and end uses, avoiding cost waste or quality risks caused by grade mismatch.
5. Flexible packaging and standardized storage: Standard packaging includes plastic woven bags, aluminum foil bags, fiber drums, and other forms, with other packaging customizable to customer needs. Aluminum foil bags provide moisture and oxygen barrier properties, suitable for moisture-sensitive reagents or food-grade products; fiber drums facilitate stacking and mechanical handling. It is recommended to store in a ventilated, low-temperature, dry warehouse, separate from oxidants and food additives, to prevent moisture caking or cross-contamination and ensure long-term product performance stability.
6. Transparent technical indicators and complete batch traceability: Detailed product test reports are provided, specifying test items, methods, limits, and corresponding batch information. For formulation-sensitive or high-requirement applications, complete data on key impurities and physicochemical indicators can be provided, facilitating customer incoming inspection comparison and small-scale trial verification, reducing internal evaluation cycles and procurement uncertainty.
