Ethyl phosphate(2-) is an organophosphate oxoanion that is the dianion of ethyl phosphate arising from deprotonation of both OH groups of the phosphate.
Ethyl phosphate has a role as a metabolite, an epitope and a phosphoantigen.
Ethyl phosphate is a conjugate base of an ethyl hydrogen phosphate(1-).

Chemical Properties
Ethyl phosphate contains phosphorus in a phosphate ester structure and can participate in reactions characteristic of phosphate esters.
Its physical and chemical properties depend strongly on whether the compound is monoethyl phosphate, diethyl phosphate, or another ethyl-substituted phosphate ester.
Ethyl phosphate derivatives can be used as phosphorus sources in chemical synthesis and as intermediates for the preparation of other organophosphorus compounds.
Uses
Ethyl phosphate compounds are used in the chemical industry as intermediates for the synthesis of phosphorus-containing chemicals.
They may be incorporated into flame-retardant systems because phosphorus-containing compounds can contribute to flame-retardant performance.
Certain ethyl phosphate derivatives are also used as plasticizers and functional additives in polymer formulations.
They can be used in specialty chemical formulations, extraction processes, and other applications requiring phosphate ester functionality.
Industrial Applications
Chemical synthesis
Flame retardant formulations
Plasticizers
Polymer additives
Phosphorus-containing specialty chemicals
Chemical intermediates
Extraction and separation processes
Handling and Storage
Ethyl phosphate should be stored in tightly closed containers in a cool, dry, and well-ventilated area.
Protect the material from excessive heat, direct sunlight, and incompatible substances.
Appropriate personal protective equipment, including protective gloves and safety glasses, should be used when handling the material.
Important Note
The name "Ethyl phosphate" can refer to more than one specific chemical, including monoethyl phosphate and diethyl phosphate.
Therefore, the exact CAS number, molecular formula, molecular weight, melting point, boiling point, and other technical specifications should be determined from the specific product or grade being described.
