(monopotassium dihydrogen phosphate)
Monopotassium dihydrogen phosphate (KH₂PO₄), a water-soluble salt with CAS No. 7778-77-0, serves as a critical component in agricultural fertilizers, food additives, and laboratory buffers. Its molecular stability under diverse pH conditions (2.4–7.2) makes it ideal for precision applications. Global demand surged by 12% between 2020–2023, driven by advancements in controlled-release fertilizer technologies.
With 99.5% purity in pharmaceutical-grade variants, KH₂PO₄ outperforms sodium dihydrogen phosphate dihydrate (NaH₂PO₄·2H₂O) in solubility (22.6 g/100mL vs. 18.3 g/100mL at 20°C). The crystalline structure enables slow nutrient release, reducing fertilizer application frequency by 30% in field trials. Advanced purification processes eliminate heavy metal contaminants below 0.001ppm, meeting USP/EP standards.
