It is a colorless to pale yellow crystalline solid that is insoluble in water but soluble in organic solvents. bis-(4-benzyl-phenyl)-ether is characterized by its symmetrical structure, featuring two benzyl-phenyl groups connected by an oxygen atom. It is commonly used as a ligand in coordination chemistry, particularly in the synthesis of metal complexes, due to its ability to form stable chelate rings with metal ions. Additionally, it has applications in the pharmaceutical industry and as a precursor in the synthesis of various organic compounds. Bis-(4-benzyl-phenyl)-ether is also known for its potential use in materials science, such as in the development of new polymers and as a component in the production of specialty chemicals.
The CAS Registry Mumber 1990-04-1 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,9,9 and 0 respectively; the second part has 2 digits, 0 and 4 respectively. Calculate Digit Verification of CAS Registry Number 1990-04: (6*1)+(5*9)+(4*9)+(3*0)+(2*0)+(1*4)=91 91 % 10 = 1 So 1990-04-1 is a valid CAS Registry Number.
