What is Disodium Hydrogen Phosphate Dihydrate?
Disodium Hydrogen Phosphate Dihydrate (Na2HPO4·2H2O) is a chemical compound. It is used in various industries like pharmaceuticals, water treatment, and agriculture. The major use is seen in the food industry as a pH buffer, emulsifier, and thickening agent. Disodium Hydrogen Phosphate Dihydrate is a white, crystalline powder that is highly soluble in water. It is an ionic compound consisting of two sodium cations (Na+) and one phosphate anion (HPO42-), with two water molecules (H2O) attached to each sodium ion. In addition, it is often used in biological and biochemical research as a buffering agent to maintain pH in various chemical reactions.
It is important to handle disodium hydrogen phosphate dihydrate with care, as it can cause skin and eye irritation and may be harmful if ingested or inhaled in large quantities.

- Laboratory Use: Disodium Hydrogen Phosphate Dihydrate is used in laboratory settings as a buffer and as a reagent for the preparation of other chemicals.
- Cosmetics: It is used in cosmetics as a pH adjuster and as a buffering agent.
- Medical Use: Disodium Hydrogen Phosphate Dihydrate is used in medicine as a laxative and as a buffer in some medical procedures.
- Fertilizers: It is used as a source of phosphorus in fertilizers for agricultural purposes.
Overall, Disodium Hydrogen Phosphate Dihydrate has a wide range of uses in various industries due to its buffering, emulsifying, and pH-adjusting properties.
Uses of Disodium Hydrogen Phosphate Dihydrate in Pharmaceutical
- Buffering Agent: Disodium Hydrogen Phosphate Dihydrate is commonly used as a buffering agent in pharmaceutical formulations. The pH of a medication can affect its stability, solubility, and bioavailability. By using Disodium Hydrogen Phosphate Dihydrate as a buffering agent, the pH of a medication can be kept within a narrow range, which helps to maintain its chemical stability and effectiveness.
For example, Disodium Hydrogen Phosphate Dihydrate is often used as a buffering agent in eye drops to maintain the pH of the solution within a range that is compatible with the delicate tissues of the eye.
- Electrolyte Replenisher: Disodium Hydrogen Phosphate Dihydrate is also used as an electrolyte replenisher in IV fluids. Electrolytes are important minerals that are essential for many cellular functions, such as muscle contraction, nerve transmission, and fluid balance. When a person becomes dehydrated or loses electrolytes due to illness, IV fluids containing Disodium Hydrogen Phosphate Dihydrate can be used to restore the balance of electrolytes in the body.
- Laxative: Disodium Hydrogen Phosphate Dihydrate is sometimes used as a laxative to relieve constipation. When taken orally, Disodium Hydrogen Phosphate Dihydrate draws water into the intestines, which helps to soften the stool and make it easier to pass. It is usually taken in combination with another laxative, such as sodium bicarbonate, to increase its effectiveness.
- Contrast Agent: Disodium Hydrogen Phosphate Dihydrate is used as a contrast agent in medical imaging procedures such as X-rays, CT scans, and MRI scans. Contrast agents are substances that are injected into the body to enhance the contrast between different tissues or organs. In the case of Disodium Hydrogen Phosphate Dihydrate, it is used as a radiopaque contrast agent for X-rays and CT scans. When injected into the body, it absorbs X-rays and appears white on the image, making it easier to detect abnormalities or diseases.
In summary, Disodium Hydrogen Phosphate Dihydrate is a versatile compound that is widely used in the pharmaceutical industry. Its uses as a buffering agent, electrolyte replenisher, laxative, and contrast agent make it an important ingredient in many different types of medications and medical procedures.
