3',5'-Difluoro-thyronine is a synthetic derivative of the naturally occurring thyroid hormone thyronine, characterized by the presence of two fluorine atoms at the 3' and 5' positions of the molecule. This modification enhances its stability and resistance to deiodination, a process that typically deactivates thyroid hormones. As a result, 3',5'-difluoro-thyronine exhibits a longer half-life in the body compared to its natural counterpart, which can be advantageous in maintaining stable hormone levels over time. The compound has been studied for its potential therapeutic applications, particularly in conditions where thyroid hormone regulation is compromised. Its unique properties make it a subject of interest in endocrinological research and drug development.
The CAS Registry Mumber 456-85-9 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 4,5 and 6 respectively; the second part has 2 digits, 8 and 5 respectively. Calculate Digit Verification of CAS Registry Number 456-85: (5*4)+(4*5)+(3*6)+(2*8)+(1*5)=79 79 % 10 = 9 So 456-85-9 is a valid CAS Registry Number.
