p-Tolyl-phosphonic acid-difluoride, also known as 4-methylphenylphosphonic difluoride, is an organophosphorus compound with the chemical formula C7H7FO2P. It is a colorless to pale yellow liquid that is soluble in organic solvents. p-tolyl-phosphonic acid-difluoride is primarily used as a reagent in organic synthesis, particularly in the formation of carbon-phosphorus bonds and as a coupling agent in the synthesis of various phosphorus-containing compounds. It is also employed in the preparation of agrochemicals and pharmaceuticals. Due to its reactivity, p-tolyl-phosphonic acid-difluoride requires careful handling and is typically stored under an inert atmosphere to prevent unwanted reactions.

701-32-6 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 701-32-6 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 7,0 and 1 respectively; the second part has 2 digits, 3 and 2 respectively.Calculate Digit Verification of CAS Registry Number 701-32:
(5*7)+(4*0)+(3*1)+(2*3)+(1*2)=46
46 % 10 = 6
So 701-32-6 is a valid CAS Registry Number.
