Background:
N-Acetyl-L-thyroxine is an acetylated derivative of L-thyroxine .1It only weakly binds to thyroxine-binding globulin (TBG) in isolated human serum with a relative binding affinity of 25 compared with L-thyroxine. N-Acetyl-L-thyroxine is also a potential impurity in commercial preparations of L-thyroxine.2
