Usage

Description

Sodium Dihydrogen Phosphate occurs as two forms: the crystal form (dihydrate) called Sodium Dihydrogen Phosphate (crystal) and anhydrous form called Sodium Dihydrogen Phosphate (anhydrous) It is used as an acidity regulator and sequestrant in foods. It is used as a pH buffer (baking powders, fleet enema solution, electroplating baths, and acid cleaners), emulsifier, laboratory reagent, metal phosphating reagent, and textile dyeing/printing auxiliary. It is also used to treat boiled water and waste waster and to remove halogen from waste gases. Furthermore, it is used as a cattle feed supplement, as nutritional supplement in food, in dentrifice formulations, in vitreous enamel frits, for the synthesis of pharmaceuticals, and as a phosphate source for micro-organisms in effluent treatment.

Uses

Different sources of media describe the Uses of 13472-35-0 differently. You can refer to the following data:
1. Sodium dihydrogen phosphate dihydrate acts as buffering capacity reagent in molecular biology, biochemistry and chromatography. It is used in the preparation of biological buffers. It is also used in the purification of antibodies, as a laxative and, in combination with other sodium phosphates.Sodium phosphate monobasic dihydrate is a reagent with very high buffering capacity widely used in molecular biology, biochemistry and chromatography. Sodium phosphate dibasic is highly hygroscopic and water soluble.Recommended chemicals for the preparation of phosphate buffers are sodium dihydrogen phosphate dihydrate，NaH2PO4.2H2O(mol. wt.156.0)，disodium hydrogen phosphate dihydrate，Na2HPO4.2H2O (mol. wt.178.0), and sodium hydroxide pellets.
2. Sodium dihydrogen phosphate dihydrate acts as buffering capacity reagent in molecular biology, biochemistry and chromatography. It is used in the preparation of biological buffers. It is also used in the purification of antibodies, as a laxative and, in combination with other sodium phosphates
3. Sodium dihydrogen phosphate dihydrate is typically used as a phosphate buffer system component for downstream biomolecule chromatography steps or final liquid formulation.Due to its low microbial and endotoxin limits, Sodium dihydrogen phosphate dihydrate Emprove? Expert is especially suitable for high-risk applications.

Biochem/physiol Actions

Sodium phosphate monobasic also referred to as sodium dihydrogen phosphate is a chemical reagent possesses high buffering capacity and is used for preparing biological buffers. It was used as a phosphate supplement for determining whether phosphate supplementation can prevent rickets in very low birth weight infants with prenatal deficiency of phosphate.
