Alkyl phosphates belong to a group of organic compounds called organophosphates. They are esters of phosphoric acid H 3 PO 4 and corresponding alcohol. For example, the formula of methyl phosphate is CH 3-H 2 PO 4, dimethyl phosphate – (CH 3) 2 HPO 4 and trimethyl phosphate – (CH 3) 3 PO 4. Alkyl phosphates are widely distributed in nature ...
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.
Phosphate esters have the general structure P(=O)(OR) 3 feature P(V). Such species are of technological importance as flame retardant agents, and plasticizers. Lacking a P−C bond, these compounds are in the technical sense not organophosphorus compounds but esters of phosphoric acid. Many derivatives are found in nature, such as ...
General ester of phosphonic acid; in fact, the phosphorus has a formal charge of +1, the oxygen above it has a formal charge of −1, and the bond between them is single. In organic chemistry, phosphonates or phosphonic acids are organophosphorus compounds containing C−PO(OR) 2 groups, where R is an organic group (alkyl, aryl).
Sodium hexametaphosphate is the alkali salt of one of the series of polymetaphosphoric acids (acids formed by the polymerization of phosphate groups). [14] Hexametaphosphoric acid was first made in 1825 by the German chemist Johann Frederich Philipp Engelhart (1797-1853). [15]

Tris(1,3-dichloroisopropyl)phosphate (TDCPP) is a chlorinated organophosphate. Organophosphate chemicals have a wide variety of applications and are used as flame retardants , pesticides , plasticizers , and nerve gases .
Phosphoryl chloride is used on an industrial scale for the manufacture of phosphate esters (organophosphates). These have a wide range of uses, including as flame retardants (bisphenol A diphenyl phosphate, TCPP and tricresyl phosphate), plasticisers for PVC and related polymers (2-ethylhexyl diphenyl phosphate) and hydraulic fluids.
