2,2,4,4-tetramethyl-1-phenyl-phospholane 1-oxide, also known as TMPO, is an organophosphorus compound with the chemical formula C12H21OP. It is a colorless liquid that is soluble in organic solvents and has a molecular weight of 214.28 g/mol. TMPO is a chiral compound, meaning it has a non-superimposable mirror image, and it is widely used as a ligand in asymmetric catalysis, particularly in the development of chiral catalysts for various chemical reactions. Its unique structure, featuring a phosphorus atom bonded to a phenyl group and two methyl groups, as well as two additional methyl groups on the phosphorus, contributes to its stability and reactivity. TMPO is also known for its ability to form complexes with transition metals, which can enhance the selectivity and efficiency of certain chemical transformations.

68305-37-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 68305-37-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,8,3,0 and 5 respectively; the second part has 2 digits, 3 and 7 respectively.Calculate Digit Verification of CAS Registry Number 68305-37:
(7*6)+(6*8)+(5*3)+(4*0)+(3*5)+(2*3)+(1*7)=133
133 % 10 = 3
So 68305-37-3 is a valid CAS Registry Number.
