DL-Tyrosine, O-(4-hydroxy-3-methylphenyl)-3,5-diiodo, also known as 3,5-Diiodo-L-tyrosine or 3,5-Diiodo-DL-tyrosine, is a synthetic derivative of the amino acid tyrosine. It features a 4-hydroxy-3-methylphenyl group attached to the oxygen atom of the hydroxyl group in the tyrosine molecule, and two iodine atoms are present at the 3rd and 5th positions of the phenyl ring. DL-Tyrosine, O-(4-hydroxy-3-methylphenyl)-3,5-diiodo- is primarily used in scientific research and pharmaceutical applications, particularly in the study of thyroid function and the development of radiopharmaceuticals for imaging and treatment of thyroid disorders. The presence of iodine atoms in the molecule makes it a potential candidate for radioiodine therapy, which is a common treatment for hyperthyroidism and thyroid cancer.
The CAS Registry Mumber 4080-14-2 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,0,8 and 0 respectively; the second part has 2 digits, 1 and 4 respectively. Calculate Digit Verification of CAS Registry Number 4080-14: (6*4)+(5*0)+(4*8)+(3*0)+(2*1)+(1*4)=62 62 % 10 = 2 So 4080-14-2 is a valid CAS Registry Number.
