It is a derivative of phospholane, a heterocyclic compound with a phosphorus atom in the ring. This specific compound features a methyl group at the 2-position, and three phenyl groups attached to the 1, 2, and 5 positions of the phospholane ring. The 1-oxide designation indicates the presence of an oxygen atom bonded to the phosphorus atom, forming a phosphine oxide. 2-methyl-1,2,5-triphenyl-phospholane 1-oxide is known for its potential applications in organic synthesis, particularly as a ligand in transition metal-catalyzed reactions, and for its unique electronic properties that can influence its reactivity and stability.
The CAS Registry Mumber 1475-80-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,4,7 and 5 respectively; the second part has 2 digits, 8 and 0 respectively. Calculate Digit Verification of CAS Registry Number 1475-80: (6*1)+(5*4)+(4*7)+(3*5)+(2*8)+(1*0)=85 85 % 10 = 5 So 1475-80-5 is a valid CAS Registry Number.
