Tris-(4-trimethylsilylphenyl)-phosphinoxide, also known as TTMSP, is a phosphorus-containing organosilicon compound with the chemical formula (C9H15Si)3PO. It is a colorless, crystalline solid that is soluble in common organic solvents. TTMSP is widely used as a ligand in coordination chemistry, particularly in the synthesis of transition metal complexes, due to its ability to stabilize metal centers and its steric bulk, which can influence the reactivity and selectivity of the resulting complexes. Additionally, it has applications in the field of materials science, such as in the development of new catalysts and as a component in the synthesis of advanced materials with unique electronic and optical properties.
The CAS Registry Mumber 18848-94-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,8,8,4 and 8 respectively; the second part has 2 digits, 9 and 4 respectively. Calculate Digit Verification of CAS Registry Number 18848-94: (7*1)+(6*8)+(5*8)+(4*4)+(3*8)+(2*9)+(1*4)=157 157 % 10 = 7 So 18848-94-7 is a valid CAS Registry Number.
