1-Oxo-1,2-diphenyl-1λ5-phospholan-3-one is a phosphorus-containing organic compound with the molecular formula C16H13O2P. It is a derivative of the phospholane ring system, featuring a phosphorus atom bonded to two carbon atoms and a single oxygen atom, with an additional carbonyl group (C=O) at the 1-position. 1-oxo-1,2-diphenyl-1λ5-phospholan-3-one is characterized by its aromatic phenyl groups attached to the phospholane ring, which contribute to its stability and reactivity. It is often used in organic synthesis as a building block for more complex molecules, particularly in the preparation of phosphorus-containing heterocycles and as a ligand in coordination chemistry. The compound's properties, such as its reactivity towards nucleophiles and electrophiles, make it a valuable intermediate in the synthesis of pharmaceuticals and materials with unique electronic properties.

40203-58-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 40203-58-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 4,0,2,0 and 3 respectively; the second part has 2 digits, 5 and 8 respectively.Calculate Digit Verification of CAS Registry Number 40203-58:
(7*4)+(6*0)+(5*2)+(4*0)+(3*3)+(2*5)+(1*8)=65
65 % 10 = 5
So 40203-58-5 is a valid CAS Registry Number.
