MKP Potassium dihydrogen phosphate is typically produced through the neutralization of phosphoric acid with potassium hydroxide or potassium carbonate. It is valued for its high solubility in water and its ability to promote plant growth efficiently.

Classification of Potassium dihydrogen phosphate:

Potassium dihydrogen phosphate (MKP) can be classified into different grades based on purity and intended use:

1.Agricultural Grade: Contains lower purity levels, typically used as a fertilizer to provide essential nutrients to plants.

2.Food Grade: High purity suitable for food applications, ensuring safety and compliance with food regulations.

3.Pharmaceutical Grade: Extremely high purity for use in medicinal formulations, adhering to strict quality standards.

4.Technical Grade: Often used in industrial applications, such as buffering solutions and chemical manufacturing, with varying purity levels.

5.Optical Grade: Ultrapure Potassium dihydrogen phosphate (MKP) used in laser applications, requiring exceptional clarity and minimal impurities.

Agricultural Grade Potassium Dihydrogen Phosphate (MKP): This grade typically contains lower purity levels, around 98% or higher, and is used primarily as a fertilizer. It provides essential potassium and phosphorus nutrients to crops, promoting healthy growth and development. This grade is formulated to enhance soil fertility and can be used in various agricultural applications, including foliar sprays and soil amendments.

Industrial Grade Potassium Dihydrogen Phosphate: This grade may vary in purity but is generally used for nonfood applications. It often serves as a buffering agent, pH regulator, and in the formulation of various chemical processes. Industrial grade Potassium dihydrogen phosphate (MKP) can also be employed in manufacturing and chemical reactions where high purity is not as critical as in food or pharmaceutical applications.
