Product Description

Sodium dihydrogen phosphate




1. Chemical name: Sodium dihydrogen phosphate

2. Molecular formula: NaH2PO4, NaH2PO4·H2O, NaH2PO4·2H2O

3. Molecular weight: Anhydrate: 119.98; Monohydrate: 137.99; Dihydrate: 156.01

4. CAS: Anhydrate: 7558-80-7; Monohydrate: 10049-21-5; Dihydrate: 13472-35-0

5. Performance: colorless columnar crystal. Odorless. Slightly deliquescent. Relative density 2.04. Melting point 60ºC. soluble in water. Insoluble in ethanol. When heated below 100ºC, it can dissolve in crystal water to form a monohydrate salt. When heated to 100°C, it loses crystal water and becomes anhydrous, and when heated further, it becomes sodium metaphosphate.

6. Usage: Buffer; quality improver; emulsifier; nutritional supplement; antioxidant synergist; salt water penetration aid; sugar clarifier; stabilizer; gelling agent; poultry scalding agent.

7. Packaging: lined with polyethylene plastic bag, outer composite plastic woven bag, net weight of each bag is 25 kg.

8. Storage and transportation: It should be stored in a dry, ventilated and clean warehouse.

Phosphates are often used in foods and in water treatment. The pH of such formulations is generally adjusted by mixtures of various sodium phosphates, such as this salt. The sodium chloride equivalent value, or E-Value, is 0.49. It is soluble in 4.5 parts water.

1.Feed additive

It is added in animal feed, toothpaste, and evaporated milk. It is used as a thickening agent and emulsifier.

2.Detection of magnesium

Monosodium phosphate is used to detect the presence of magnesium ions in salts. Formation of a white precipitate on the addition of ammonium chloride, ammonium hydroxide and monosodium phosphate to an aqueous or dilute HCl solution of the salt indicates presence of magnesium ions.

3.Food Industry

In food industry and fermentation industry, it can also be used as buffering agent, raw material of baking powder, adhesive and curing agent for bread and sauce, sour agent for powder, and quality improver for evaporated milk.Also can make cheese and other dairy products, meat, fish products stabilizer, binder, baking powder buffer, salting with mixed salt, etc.

4.Industrial Use

Sodium dihydrogen phosphate is used for boiler water treatment and electroplating.It is a raw material for the manufacture of sodium hexametaphosphate and polypolyphosphate.It is also used in the manufacture of detergents, metal detergents, and as dyes and pigment precipitators.
