General description
Ammonium sodium phosphate dibasic tetrahydrate (Ammonium sodium hydrogen phosphate) is a colorless ammonium salt. On heating, it undergoes decomposition to afford sodium polyphosphate.
Application
Ammonium sodium phosphate dibasic tetrahydrate (Sodium ammonium phosphate tetrahydrate) may be used in the following studies:
- To compose the growth medium during the biocatalytic synthesis of 4-fluorocatechol.
- Preparation of microcosmic salt beads, which are used in qualitative analysis.
