AI Product Description
*The following content is generated by AI and is for reference only.
Dibasic sodium phosphate, chemically known as disodium hydrogen phosphate (Na₂HPO₄), is a versatile inorganic compound widely utilized across various industrial and scientific sectors. Its molecular formula is typically represented as Na₂HPO₄, though it frequently exists as a hydrate, with the heptahydrate form (Na₂HPO₄·7H₂O) being the most common commercial variant. The anhydrous substance corresponds to CAS number 7558-79-4, while the heptahydrate is identified by CAS number 10039-32-4. This white, crystalline powder or granular solid is highly soluble in water, forming alkaline solutions that make it an essential buffering agent in biological and chemical applications.
In the pharmaceutical industry, dibasic sodium phosphate serves as a critical excipient for stabilizing drug formulations and adjusting pH levels to ensure optimal efficacy and shelf life. It is also a key ingredient in effervescent tablets and intravenous fluids. In food processing, it functions as a leavening agent, emulsifier, and acidity regulator, commonly found in processed meats, baked goods, and dairy products to improve texture and preservation. Furthermore, its role extends to water treatment, where it acts as a corrosion inhibitor and scale control agent in cooling towers and boiler systems, protecting infrastructure from mineral buildup and degradation.
The compound is indispensable in laboratory settings for preparing phosphate buffers used in cell culture, protein purification, and DNA analysis, maintaining stable pH environments crucial for enzymatic reactions. Additionally, it finds application in agriculture as a component of fertilizers and in animal feed to balance dietary phosphorus levels. With its high solubility, stability, and safety profile when handled according to guidelines, dibasic sodium phosphate remains a fundamental chemical in modern manufacturing and research. Its ability to modulate pH effectively makes it a preferred choice for creating controlled environments in both large-scale industrial processes and delicate analytical procedures. Whether ensuring the consistency of a medication, enhancing the quality of food products, or preserving industrial equipment, this compound exemplifies the intersection of chemistry and practical utility in daily life.
