Potassium phosphate monobasic, for molecular biology, ≥98.0%. Use the product Attributes below to configure the comparison table. Also to be noted is KD*P, potassium dideuterium phosphate, with slightly different properties. Potassium phosphate is a generic term for the salts of potassium and phosphate ions including: Monopotassium phosphate (KH 2 PO 4) (Molar mass approx: 136 g/mol) Dipotassium phosphate (K 2 HPO 4) (Molar mass approx: 174 g/mol) Tripotassium phosphate (K 3 PO 4) (Molar mass approx: 212.27 g/mol) As food additives, potassium phosphates have the E number E340. Together with dipotassium phosphate (K2HPO4 (H2O)x) it is often used as a fertilizer, food additive, and buffering agent.

Single crystals are paraelectric at room temperature. 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. Monopotassium phosphate (MKP) (also, potassium dihydrogenphosphate, KDP, or monobasic potassium phosphate) is the inorganic compound with the formula KH2PO4. © 2020 Merck KGaA, Darmstadt, Germany and/or its affiliates. 7778-77-0.

Mathews, Christopher K., K. E. Van Holde, Ean R. Appling, and Spencer J. Anthony-Cahill. This protocol has been adapted from Sambrook & Russell for the preparation of potassium phosphate buffer from potassium phosphate stock solutions at various pH values. CAS Number: 7758-11-4. A1.5 ISO, reag. At room temperature it forms paraelectric crystals with tetragonal symmetry. Customer Service. to the dried substance). 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. (Select up to %1% total). Used in optical modulators and for non-linear optics such as second-harmonic generation (SHG). Millipore & Russell, D. W. (2001).
MKP powder is often used as a nutrient source in the greenhouse trade and in hydroponics. [6] When heated further, MKP decomposes, by loss of water, to potassium metaphosphate, KPO3, at 400 °C (752 °F). Eur., NF, E340, anhydrous, 98-100.5% (calc. Fertilizer-grade MKP powder contains the equivalent of 52% P2O5 and 34% K2O, and is labeled NPK 0-52-34. Questions? Sigma-Aldrich Products are sold exclusively through Sigma-Aldrich, Inc.
