Diphenyl-<1-propyl-butyl>-phosphinoxyd, also known as diphenyl-(1-propylbutyl)-phosphine oxide, is an organophosphorus compound characterized by a phosphine oxide functional group. It consists of two phenyl rings attached to a phosphorus atom, which is further connected to a 1-propylbutyl chain. This chemical is often used as a ligand in coordination chemistry, particularly in the formation of transition metal complexes. Its unique structure allows it to stabilize and modulate the properties of metal centers in various applications, including catalysis and materials science. The compound is also of interest in the synthesis of other organophosphorus derivatives due to its potential reactivity and the ability to form stable intermediates in chemical transformations.
The CAS Registry Mumber 736-73-2 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 7,3 and 6 respectively; the second part has 2 digits, 7 and 3 respectively. Calculate Digit Verification of CAS Registry Number 736-73: (5*7)+(4*3)+(3*6)+(2*7)+(1*3)=82 82 % 10 = 2 So 736-73-2 is a valid CAS Registry Number.
