Understanding the chemical properties of raw materials is fundamental for any B2B buyer in the chemical and pharmaceutical sectors. Sodium Pyrophosphate Dibasic, known by its CAS number 7758-16-9, is a compound widely used in laboratory research for its unique characteristics. As a leading chemical manufacturer and supplier, NINGBO INNO PHARMCHEM CO.,LTD. is dedicated to providing detailed information about the chemicals we provide, ensuring our clients can make informed purchasing decisions. Let’s delve into the key chemical properties of Sodium Pyrophosphate Dibasic.

Sodium Pyrophosphate Dibasic, with the molecular formula H2P2O7•2Na, is a disodium salt of pyrophosphoric acid. It typically presents as a white powder. The molecular weight is approximately 221.94 g/mol. Chemically, it is an inorganic compound that belongs to the class of pyrophosphates. Its structure involves two sodium ions balancing the charge of the pyrophosphate anion. The purity of the compound is a critical parameter, with most commercial grades offering an assay of 99% or higher, which is essential for precise chemical applications.

One of the most significant chemical properties of Sodium Pyrophosphate Dibasic is its solubility. It is fully miscible in water, meaning it dissolves readily to form a clear, colorless solution. For example, at 20°C, a 0.1 M solution is typically clear. This high water solubility makes it extremely convenient for preparing aqueous solutions, especially buffer systems where precise concentrations are required. In contrast, it is insoluble in alcohol and ammonia. This behavior is a key factor in its selection for aqueous-based research protocols. If you need to buy a water-soluble buffer component, this is an excellent choice.

The stability of Sodium Pyrophosphate Dibasic is another crucial property. Under recommended storage conditions, typically in a cool, dry place and in tightly sealed containers, the compound remains stable. This ensures its efficacy over time, allowing researchers and procurement managers to maintain a consistent supply without significant degradation. The pH of an aqueous solution is also an important characteristic; a 0.1 M solution typically exhibits a pH between 3.5 and 4.5, indicating its acidic nature in solution, which is beneficial for buffering in this range.
