Mono potassium phosphate MKP (also potassium dihydrogen phosphate, KDP, or monobasic potassium phosphate, MKP or potassium phosphate monobasic) -- KH2PO4 -- is a soluble salt which is used as a fertilizer, a food additive and a fungicide. Mono potassium phosphate is a source of phosphorus and potassium. Mono potassium phosphate is also a buffering agent. When used in fertilizer mixtures with urea and ammonium phosphates, Mono potassium phosphate minimizes escape of ammonia by keeping the pH at a relatively low level.

Potassium Phosphate - Monobasic: Potassium biphosphate or acid phosphate; potassium dihydrogen phosphate; mono potassium phosphate. KH2PO4; mol. wt. 136.09. Colorless crystals or white, granular powder; permanent in air; at 400° loses H2O, forming metaphosphate. d. 2.34. Soluble in about 4.5 parts water; insoluble in alcohol. pH: 4.4-4.7.

MKP is used to prevent calcium kidney stones. It is also used to decrease the amount of ammonia in urine, thereby reducing odor and skin irritation caused by high-ammonia urine. This medication is also given to help certain antibiotics for bladder infectionswork better.

Fertilizer grade MKP contains the equivalent of 52% P2O5 and 34% K2O, and is labeled 0-52-34. MKP is often used as a nutrient source in the greenhouse trade and in hydroponics.

MKP is one of the components of Gatorade and is used as an additive in cigarettes.

As a crystal, MKP is noted for its non-linear optical properties. Used in optical modulators and for non-linear optics such as SHG (second harmonic generation).

Also to be noted is KDP, Potassium Dideuterium Phosphate, with slightly different properties. Highly deuterated KDP is used in nonlinear frequency conversion of laser light instead of protonated (regular) KDP due to the fact that the replacement of protons with deuterons in the crystal shifts the third overtone of the strong OH molecular stretch to longer wavelengths, moving it mostly out of the range of the fundamental line at ~1,064nm of neodymium based lasers. Regular KDP has absorbance at this wavelength of around 4.7-6.3%/cm of thickness while highly deuterated KDP has absorbance's of typically less than .8%/cm.
