4-Hydroxy-3,5-diiod-α-methyl-phenyl-alanin-aethylester, also known as 4-Hydroxy-3,5-diiodo-α-methylphenylalanine ethyl ester, is a synthetic organic compound with the chemical formula C11H12INO4. It is a derivative of phenylalanine, an essential amino acid, featuring a hydroxyl group at the 4-position, two iodine atoms at the 3 and 5 positions, and an α-methyl group. The ethyl ester functional group is attached to the carboxylic acid moiety, making it a lipophilic compound. This chemical is primarily used in pharmaceutical research and development, particularly in the synthesis of radiopharmaceuticals for imaging studies, such as single-photon emission computed tomography (SPECT). Its unique structure allows for specific targeting and imaging of certain biological processes, making it a valuable tool in medical diagnostics.
The CAS Registry Mumber 7373-63-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,3,7 and 3 respectively; the second part has 2 digits, 6 and 3 respectively. Calculate Digit Verification of CAS Registry Number 7373-63: (6*7)+(5*3)+(4*7)+(3*3)+(2*6)+(1*3)=109 109 % 10 = 9 So 7373-63-9 is a valid CAS Registry Number.
