Diethyl phosphorofluoridothioate, also known as DFP, is a highly toxic organophosphorus compound that acts as a potent inhibitor of acetylcholinesterase, an enzyme responsible for breaking down the neurotransmitter acetylcholine. This inhibition leads to the accumulation of acetylcholine in the synaptic cleft, causing overstimulation of the nervous system. DFP is a colorless, oily liquid with a pungent odor and is used as a chemical warfare agent, insecticide, and pesticide. Due to its extreme toxicity, it poses significant risks to human health, including respiratory failure, seizures, and even death. Proper safety measures and personal protective equipment are crucial when handling DFP to minimize exposure and potential health hazards.

Check Digit Verification of cas no

The CAS Registry Mumber 358-75-8 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 3,5 and 8 respectively; the second part has 2 digits, 7 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 358-75:
(5*3)+(4*5)+(3*8)+(2*7)+(1*5)=78
78 % 10 = 8
So 358-75-8 is a valid CAS Registry Number.

New General Synthesis of Organophosphorus P-F Compounds via Reaction of Azolides of Phosphorus Acids with Acyl Fluorides: Novel Route to 2-Deoxynucleosidyl Phosphorofluoridates and Phosphorodifluoridates

Dabkowski, Wojciech,Michalski, Jan,Wasiak, Jacek,Cramer, Friedrich

, p. 817 - 820 (2007/10/02)

Tetra- and tri-coordinate P-N-imidazole derivatives and their structural analogous react smoothly with acyl fluorides to give the corresponding P-F compounds an almost quantitative yield.This method has been successfully applied to produce 2-deoxynucleosidyl phosphorofluoridates and phosphorodifluoridates.

A NEW SYNTHESIS OF PHOSPHOROFLUORIDATES OF BIOLOGICAL INTEREST. THE REACTION OF PHOSPHOROAZOLIDES WITH BENZOYL FLUORIDE

Dabkowski, Wojciech,Cramer, Friedrich,Michalski, Jan

, p. 3561 - 3562 (2007/10/02)

Phosphoroazolides, including nucleoside derivatives, can be converted smoothly into the corresponding phosphorofluoridates by reaction with benzoyl fluoride.From these compounds oligonucleotides containing P-F instead of P-OH can be prepared.
