It is a colorless to pale yellow liquid with a molecular weight of 302.30 g/mol. diphenyl-phosphinic acid isopropenyl ester is characterized by the presence of a phosphinic acid group, which is a derivative of phosphinic acid, and an isopropenyl (allyl) group, which is a three-carbon chain with a double bond between the first and second carbon atoms. Diphenyl-phosphinic acid isopropenyl ester is used as a ligand in coordination chemistry, particularly in the formation of transition metal complexes, and has potential applications in catalysis and material science. It is also known for its role in the synthesis of various organic compounds and pharmaceuticals.
The CAS Registry Mumber 1733-53-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,7,3 and 3 respectively; the second part has 2 digits, 5 and 3 respectively. Calculate Digit Verification of CAS Registry Number 1733-53: (6*1)+(5*7)+(4*3)+(3*3)+(2*5)+(1*3)=75 75 % 10 = 5 So 1733-53-5 is a valid CAS Registry Number.
