In organic chemistry, organophosphates (also known as phosphate esters, or OPEs) are a class of organophosphorus compounds with the general structure O=P(OR) 3, a central phosphate molecule with alkyl or aromatic substituents. [1] They can be considered as esters of phosphoric acid. Organophosphates are best known for their use as pesticides.
Skydrol is a brand name of fire-resistant hydraulic fluid [1] used in aviation and aerospace applications. It is a phosphate ester-based fluid that is known for its excellent fire resistance and ability to withstand extreme temperature and pressure conditions.
The term phosphate is also used in organic chemistry for the functional groups that result when one or more of the hydrogens are replaced by bonds to other groups. These acids, together with their salts and esters , include some of the best-known compounds of phosphorus, of high importance in biochemistry , mineralogy , agriculture , pharmacy ...
With the formula (HO) 2 P(O)CH 2 NHCH 2 CO 2 H, this derivative of glycine is one of the most widely used herbicides. Bisphosphonates are a class of drugs to treat osteoporosis. The nerve gas agent sarin, containing both C–P and F–P bonds, is a phosphonate. [citation needed] Phosphinates feature two P–C bonds, with the general formula R 2 ...
Di(2-ethylhexyl)phosphoric acid (DEHPA or HDEHP) is an organophosphorus compound with the formula (C 8 H 17 O) 2 PO 2 H. The colorless liquid is a diester of phosphoric acid and 2-ethylhexanol. It is used in the solvent extraction of uranium, vanadium and the rare-earth metals. [1]
Diethyl chlorophosphate is an organophosphorus compound with the formula (C 2 H 5 O) 2 P(O)Cl. As a reagent in organic synthesis, it is used to convert alcohols to the corresponding diethylphosphate esters. It is a colorless liquid with a fruity odor. It is a corrosive, and as a cholinesterase inhibitor, highly toxic through dermal absorption. [1]
It is an ester of phosphoric acid with the nucleoside guanosine. GMP consists of the phosphate group, the pentose sugar ribose, and the nucleobase guanine; hence it is a ribonucleotide monophosphate. Guanosine monophosphate is commercially produced by microbial fermentation. [1] As an acyl substituent, it takes the form of the prefix guanylyl-.
The most recent driver to make their Formula One debut is Jack Doohan, who debuted at the 2024 Abu Dhabi Grand Prix. [ 18 ] This list includes all drivers who have entered a World Championship race, including participants of the Indianapolis 500 between 1950 and 1960 when it was part of the World Championship (although not being run according ...
