Alkyl phosphate

 ( Organophosphates ) 

Alkyl phosphates belong to a group of called . They are of phosphoric acid H₃PO₄ and corresponding alcohol. For example, the formula of methyl phosphate is CH₃-H₂PO₄, dimethyl phosphate – (CH₃)₂HPO₄ and trimethyl phosphate – (CH₃)₃PO₄. Alkyl phosphates are widely distributed in nature, and form the basis of most biological processes. For example, high energy metabolites such as ATP and PEP are alkyl phosphates, as are nucleic acids such as DNA and RNA. Alkyl phosphates are also important medicinally, for example the HIV drug Zidovudine is inactive until it becomes an alkyl phosphate in vivo.

Dialkyl phosphate In Dialkyl phosphates, two of the hydrogens in phosphoric acid are replaced by alkyl groups, e.g. dimethyl phosphate – (CH₃)₂HPO₄

Agricultural use Dialkyl phosphates or dialkyl phosphate esters are used in many agrochemical.

Levels in the urine have been used as a method of trying to determine levels of exposure to organophosphates; however, it is unclear how well they do this.

Health effects Exposure to dialkyl phosphate during pregnancy appears to increase the risk of ADHD.

Trialkyl phosphate In Trialkyl phosphates, all three hydrogens in phosphoric acid are replaced by alkyl groups, e.g. trimethyl phosphate – (CH₃)₃PO₄.
