Triphenylmethyl-fluorphosphoran, also known as triphenylmethyl fluorophosphine oxide, is a complex organophosphorus compound with the chemical formula (C6H5)3CP(O)F2. It is a colorless, crystalline solid that is sensitive to moisture and air, and it is typically used as a reagent in organic synthesis. The compound is formed by the reaction of triphenylmethyl chloride with silver difluorophosphate, and it is known for its ability to act as a source of the highly reactive fluorophosphorylating agent, difluorophosphoryl difluoride (F2P(O)F). Due to its reactivity, it is important to handle Triphenylmethyl-fluorphosphoran with care, using appropriate safety measures and equipment.
The CAS Registry Mumber 36121-20-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,6,1,2 and 1 respectively; the second part has 2 digits, 2 and 0 respectively. Calculate Digit Verification of CAS Registry Number 36121-20: (7*3)+(6*6)+(5*1)+(4*2)+(3*1)+(2*2)+(1*0)=77 77 % 10 = 7 So 36121-20-7 is a valid CAS Registry Number.
