(4-METHYLSULFANYL-PHENYL)-PHOSPHONIC ACID DIETHYL ESTER, with the molecular formula C12H19O3PS, is a phosphonate ester that exhibits a colorless to pale yellow liquid form accompanied by a distinctive odor. It is recognized for its applications as a flame retardant and for its insecticidal properties, which make it valuable in the production of pesticides. However, it is classified as moderately toxic, necessitating careful handling and adherence to safety measures to mitigate potential health risks from ingestion, skin contact, or inhalation.

Check Digit Verification of cas no

The CAS Registry Mumber 77918-45-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,7,9,1 and 8 respectively; the second part has 2 digits, 4 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 77918-45:
(7*7)+(6*7)+(5*9)+(4*1)+(3*8)+(2*4)+(1*5)=177
177 % 10 = 7
So 77918-45-7 is a valid CAS Registry Number.

Practical protocol for the palladium-catalyzed synthesis of arylphosphonates from bromoarenes and diethyl phosphite

Goo?en, Lukas J.,Dezfuli, Mohammad K.

, p. 445 - 448 (2007/10/03)

A greatly improved, reliable protocol for the palladium-catalyzed cross-coupling of dialkyl phosphites with aryl bromides has been developed. The use of an alcoholic solvent was the key to high yields in the synthesis of a broad variety of arylphosphonate

A direct and new convenient oxidation: Synthesis of substituted arylphosphonates from aromatics

Simeon, Fabrice,Jaffres, Paul-Alain,Villemin, Didier

, p. 10111 - 10118 (2007/10/03)

An easy synthesis of aryl phosphonates by oxidation from aryldichlorophosphines with iodine in good yields is described. Aryldichlorophosphines are obtained by reaction of phosphorous trichloride with some aromatics in presence of various Lewis acids. BiCl3 and Bi(OTf)3 are used for the first time and bismuth trichloride is, for the first time in the case of anisole or thioanisole phosphonylation, used as a true regenerable Lewis acid catalyst in a reaction of direct phosphonylation of aromatics.

SYNTHESIS OF PHOSPHONIC DICHLORIDES AND CORRELATION OF THEIR P-31 CHEMICAL SHIFTS

Grabiak, Raymond C.,Miles, James A.,Schwenzer, Gretchen M.

, p. 197 - 202 (2007/10/02)

Various mono-substituted diethyl arylphosphonates were prepared in good yield by treatment of aryl bromides or iodides with triethyl phosphite in the presence of NiCl2 or alternatively, addition of the aryl grignard reagent to diethyl phosphorochloridate.
