Description

General description

Sodium dihydrogen phosphate is an inorganic compound, which is soluble in water. Sodium dihydrogen phosphate dihydrate is used as a reagent in the development of silicate-based grouts.

Application

Sodium phosphate monobasic dihydrate has been used:

• to perform perfusion for fixed brain tissue to the validate magnetic resonance (MR) signal changes and analyze neuropathological changes in the brain
• as a component of basal salt solution to prepare biofilm minimal media (BMM) for culturing Pseudomonas aeruginosa strain PAO1
• to prepare sodium phosphate monobasic (NaH₂PO₄) stock solutions to make running buffer for capillary electrophoresis
