Tris(4(5)-(hydroxyethyl)imidazol-2-yl)phosphine, also known as THIOP, is a phosphine ligand that is widely used in homogeneous catalysis. It is a tridentate ligand, meaning it can form three bonds with a metal center, which enhances the stability and selectivity of the catalyst. THIOP is particularly noted for its ability to stabilize metal complexes in various oxidation states, making it a versatile ligand in the field of catalysis. Its structure, featuring hydroxyethyl groups attached to the imidazole rings, contributes to its solubility and its capacity to form strong bonds with metals. This ligand is often employed in the synthesis of various organic compounds and in the development of new catalytic processes, showcasing its importance in the realm of chemical research and industrial applications.

Check Digit Verification of cas no
The CAS Registry Mumber 91084-07-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,1,0,8 and 4 respectively; the second part has 2 digits, 0 and 7 respectively.Calculate Digit Verification of CAS Registry Number 91084-07:
(7*9)+(6*1)+(5*0)+(4*8)+(3*4)+(2*0)+(1*7)=120
120 % 10 = 0
So 91084-07-0 is a valid CAS Registry Number.
