Sodium Phosphate Monobasic Monohydrate CAS 10049-21-5

what is of Sodium Phosphate Monobasic Monohydrate CAS 10049-21-5

Sodium Phosphate Monobasic Monohydrate (also known as monosodium phosphate monohydrate) is an inorganic salt with the chemical formula NaH₂PO₄ ⋅ H₂O. Widely used in food processing, and life sciences, it primarily serves as a high-capacity buffering agent to maintain stable, mildly acidic pH levels.

Specification

Application Scenarios:

Food grade: acidity regulator, emulsion stabilizer and moisture retaining agent.

1. High-quality acidic leavening agent in the baking industry: In cakes, breads, biscuits and baking premixes, sodium dihydrogen phosphate monohydrate, due to its unique slightly acidic nature, can react slowly and steadily with sodium bicarbonate (baking soda) during heating, releasing carbon dioxide gas, making the flour products uniform in structure, fluffy in texture, and better in taste.

2. Stable anti-coagulation agent for dairy products and beverages: used in prepared milk, condensed milk, milk tea, and fruit juice drinks. It can adjust the pH value of the emulsion and prevent the milk protein (casein) from denaturing, agglomerating and stratifying due to acidity fluctuations during ultra-high temperature sterilization (UHT) or long-term shelf life.

3. Caking control: Compared with anhydrous substances, the monohydrated form is less likely to absorb surrounding free water when mixing solid powder foods (such as compound seasoning powder, solid soup), and can effectively keep the solid powder dry and free-flowing.

Industrial grade:

1. Boiler water circulation scale prevention and anti-corrosion: Inject into the circulating water of industrial boilers or central air conditioners as an acid regulator and scale inhibitor. It can react with calcium and magnesium hardness ions in the water to form flowing water slag, which is discharged with regular sewage discharge; at the same time, phosphate can induce the formation of a tight iron-phosphate passivation film on the inner wall of the pipe to isolate dissolved oxygen and prevent metal perforation and corrosion.

2. Metal degreasing cleaning and electroplating pre-treatment: Before hardware and auto parts are painted or electroplated, it is a formula component of powerful cleaning agents. It can not only peel off and disperse trace rust spots and dirt on the metal surface, but also provide short-term anti-rust protection for the surface of the workpiece.
