Dialkylphosphites
WebFind dialkyl phosphites and related products for scientific research at MilliporeSigma WebDialkyl alkylphosphonates are, in general, more reactive than the corresponding phosphate esters because the carbon has no unpaired electrons to contribute to allow a pπ- dπ contribution to the P-C bond. This makes the phosphorus atom of phosphonates more electrophilic than the phosphorus atom of the corresponding phosphate ester.

Alkyl phosphates belong to a group of organic compounds called organophosphates. They are esters 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 phos… WebView our Dialkyl phosphates products at Fisher Scientific.
