Triphenylvinyl-phosphorsaeurediaethylester, also known as triphenyl(vinyl)phosphine oxide or TPPO, is an organophosphorus compound characterized by its molecular formula C20H17O2P. It is a colorless to pale yellow crystalline solid with a molecular weight of 322.33 g/mol. TPPO is a derivative of triphenylphosphine, where one of the phenyl groups is replaced by a vinyl group, and the phosphorus atom is bonded to an oxygen atom, forming a phosphine oxide. Triphenylvinyl-phosphorsaeurediaethylester is primarily used as a ligand in organometallic chemistry, particularly in the synthesis of transition metal complexes, and as a reagent in various organic reactions. It is also known for its potential applications in materials science and as a precursor in the production of other phosphorus-containing compounds. Due to its reactivity and sensitivity to air and moisture, TPPO is typically handled under an inert atmosphere and stored away from light and heat.

4336-71-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 4336-71-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,3,3 and 6 respectively; the second part has 2 digits, 7 and 1 respectively.Calculate Digit Verification of CAS Registry Number 4336-71:
(6*4)+(5*3)+(4*3)+(3*6)+(2*7)+(1*1)=84
84 % 10 = 4
So 4336-71-4 is a valid CAS Registry Number.
