Upon cooling to −150 °C (−238 °F) it transforms to a ferroelectric phase of orthorhombic symmetry, and the transition temperature shifts up to −50 °C (−58 °F) when hydrogen is replaced by deuterium. Biochemistry. Customer Service. This protocol has been adapted from Sambrook & Russell for the preparation of potassium phosphate buffer from potassium phosphate stock solutions at various pH values. Yoel Sasson may be the most prolific contributor in the history of phase-transfer catalysis to the advancement of academic PTC reactions and mechanistic papers in an extremely diverse range of applications. 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 approximately 1064 nm of neodymium-based lasers. Site Use Terms Potassium phosphate monobasic, 99.99% trace metals basis, Potassium phosphate monobasic, for HPLC, LiChropur. to the dried substance). pp. As a crystal, MKP is noted for its non-linear optical properties. Molecular Cloning: A Laboratory Manual, 3 edn. 9 Products. Contact Potassium phosphate monobasic, tested according to Ph Eur, anhydrous. Monopotassium phosphate, MKP, (also potassium dihydrogenphosphate, KDP, or monobasic potassium phosphate) is the inorganic compound with the formula KH2PO4. | Privacy. MKP powder is often used as a nutrient source in the greenhouse trade and in hydroponics. (Select up to %1% total). Used in optical modulators and for non-linear optics such as second-harmonic generation (SHG). Single crystals are paraelectric at room temperature. Together with monopotassium phosphate (KH2PO4 (H2O)x), it is often used as a fertilizer, food additive, and buffering agent. Sambrook, J. A1.5 ISO, reag. Cold Spring Harbor, N.Y.: Cold Spring Harbor Laboratory Press. Potassium phosphate monobasic, for molecular biology, ≥98.0%. The salt often cocrystallizes with the dipotassium salt as well as with phosphoric acid.  Heating to 190 °C (374 °F) changes its structure to monoclinic. Regular KDP has absorbances at this wavelength of approximately 4.7–6.3% per cm of thickness while highly deuterated KDP has absorbances of typically less than 0.8% per cm. Print. Questions?
