N,N-Diphenyl-N'-diphenylphosphinyl-harnstoff, also known as N,N-diphenyl-N'-diphenylphosphinoyl-urea, is an organophosphorus compound with the chemical formula C20H18N2OP. It is a white crystalline solid that is soluble in common organic solvents such as ethanol, acetone, and dichloromethane. N.N-Diphenyl-N'-diphenylphosphinyl-harnstoff is characterized by its diphenylamine and diphenylphosphinoyl groups, which are connected through a urea linkage. It is often used as a ligand in coordination chemistry, particularly in the formation of transition metal complexes. Due to its unique structure, it can influence the electronic properties and reactivity of the complexes it forms, making it a valuable tool in the study of organometallic chemistry and catalysis.
The CAS Registry Mumber 6779-26-6 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,7,7 and 9 respectively; the second part has 2 digits, 2 and 6 respectively. Calculate Digit Verification of CAS Registry Number 6779-26: (6*6)+(5*7)+(4*7)+(3*9)+(2*2)+(1*6)=136 136 % 10 = 6 So 6779-26-6 is a valid CAS Registry Number.
