설명

일반 설명

Sodium phosphate is a colorless crystalline sodium salt. It is widely used as a buffer in molecular biology, biochemistry, and chromatographic studies. It exists in three forms: monobasic (NaH₂PO₄), dibasic (Na₂HPO₄), and tribasic (Na₃PO₄). Monobasic and dibasic forms in varying ratios are commonly used to compose the neutral sodium phosphate buffer solution.

애플리케이션

Sodium phosphate dibasic dodecahydrate may be used to prepare the 0.1M phosphate buffer having pH 7.4.
