General chemical structure of the organophosphate functional group. 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 ...
Organophosphorus chemistry is the scientific study of the synthesis and properties of organophosphorus compounds, which are organic compounds containing phosphorus. [1] They are used primarily in pest control as an alternative to chlorinated hydrocarbons that persist in the environment.
Terbufos, also known as S-((tert-butylthio)methyl) O,O-diethyl phosphorodithioate, [17] is a compound classified as an organophosphate.Terbufos consists of a central phosphorus atom, surrounded by four different groups.
Organophosphates are esters and ester derivatives of phosphoric acid. Ester derivatives include: Ester halides (Category:Organophosphorohalidates)
Organophosphate toxicity is classically associated with acetylcholinesterase inhibition. Acetylcholinesterase is an enzyme responsible for breaking down the neurotransmitter acetylcholine . Many organophosphates, especially those designed to act as nerve agents or pesticides, bind with the active site on acetylcholinesterase, preventing it from ...
In organic chemistry, phosphate or orthophosphate is an organophosphate, an ester of orthophosphoric acid of the form PO 4 RR′R″ where one or more hydrogen atoms are replaced by organic groups. An example is trimethyl phosphate, (CH 3) 3 PO 4. The term also refers to the trivalent functional group OP(O-) 3 in such esters.
Tetraethyl pyrophosphate, abbreviated TEPP, is an organophosphate compound with the formula [(C 2 H 5 O) 2 P(O)] 2 O. It is the tetraethyl derivative of pyrophosphate (P 2 O 7 4-). It is a colorless oil that solidifies near room temperature. It is used as an insecticide. The compound hydrolyzes rapidly. [3]
Dimethoate is a widely used organophosphate insecticide and acaricide. It was patented and introduced in the 1950s by American Cyanamid. Like other organophosphates, dimethoate is an acetylcholinesterase inhibitor which disables cholinesterase, an enzyme essential for central nervous system function. It acts both by contact and through ingestion.
