NINGBO INNO PHARMCHEM CO.,LTD. is committed to providing high-quality chemicals, and understanding the fundamental chemical properties of Sodium Dihydrogen Phosphate Dihydrate (NaH₂PO₄·2H₂O) is key to appreciating its wide-ranging applications. This inorganic salt is characterized by its molecular formula, which indicates the presence of sodium, hydrogen, and phosphate ions, along with two molecules of water of hydration. The dihydrate form is common and enhances its solubility and handling characteristics.

The compound presents as a white, crystalline powder, which is largely odorless. A significant characteristic is its hygroscopic nature, meaning it readily absorbs moisture from the air, necessitating careful storage in airtight containers to maintain its integrity. Its solubility in water is high, forming slightly acidic solutions with a pH typically ranging between 4.0 and 4.5 (at 50mg/mL concentration). This mildly acidic pH is a direct result of the dissociation of the dihydrogen phosphate ion (H₂PO₄⁻), which can donate a proton, contributing to its excellent buffering capabilities. Understanding these sodium dihydrogen phosphate dihydrate uses is crucial for its effective application.

The chemical structure involves ionic bonding between the sodium cation (Na⁺) and the dihydrogen phosphate anion (H₂PO₄⁻). The latter features a central phosphorus atom bonded to four oxygen atoms, with two hydrogen atoms attached to two of the oxygen atoms, facilitating its proton-donating ability. This molecular arrangement is fundamental to its functionality as a buffer and its role in various chemical reactions.
