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.
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.
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 ...
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 ...
Organophosphates are esters and ester derivatives of phosphoric acid. Ester derivatives include: Ester halides (Category:Organophosphorohalidates)
Illustrative organophosphates and related compounds: phosphatidylcholine, triphenylphosphate, cyclophosphamide, parathion, and zinc dithiophosphate. Phosphoryl thioates are thermodynamically much stabler than thiophosphates, which can rearrange at high temperature or with a catalytic alkylant to the former: [ 7 ] : 73–76
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.
Organothiophosphates or organophosphorothioates are a subclass of organophosphorus compounds and of thiophosphate compounds.They are the organic compounds that contain a phosphate group in which one or more oxygen atoms is substituted by sulfur.
