Description
Sodium phosphate occurs in several forms: monobasic (NaH2PO4), dibasic (Na2HPO4), and tribasic (Na3PO4). Most neutral sodium phosphate buffer solutions consist of mixtures of the monobasic and dibasic forms to varying degrees, depending on the desired pH.
- A table for preparation of 0.1M sodium phosphate buffer at 25°C using various proportions of sodium phosphate monobasic and sodium phosphate dibasic has been published.
- A study of the effect of freeze-thaw storage cycles on proteins in sodium phosphate and potassium phosphate buffer solutions has been reported.
- The effect of 5mM sodium phosphate on the efficacy of electrospray ionization (ESI) ion mobility spectrometry (IMS) analysis has been evaluated.
- A protocol for the purification of pyrogen-free mouse IgG1 monoclonal antibodies which uses 10 mM sodium phosphate (pH 7.4) has been published.
- An ion-pairing HPLC method for the analysis of 5-aminosalicylic acid has been reported.
- A TLC method for separation of nucleotide sugars in the study of glycosyltransferase activity has been published.
Sodium phosphate monobasic, monohydrate has a wide variety of uses:
- Sequestrant, emulsifier and buffer in foods
- Mordant in dyeing
- Weighting silk in tanning
- Manufacture of enamels, ceramics, detergents, boiler compounds
- Fireproofing agent
- In soldering and brazing instead of borax
- Reagent and buffer in analytical chemistry
- Cathartic
- Laxative
