Name: [13C6]-Thyroxine,  [13C6]-T4, [13C6]-Levothyroxin, (S)-2-amino-3-(4-(4-hydroxy-3,5-diiodophenoxy-1,2,3,4,5,6-13C6)-3,5-diiodophenyl)propanoic acid.

Thyroxine (T4) is the main hormone secreted into the bloodstream by the thyroid gland. It is the inactive form and most of it is converted to an active form called triiodothyronine by organs such as the liver and kidneys.

Stable isotope labeled Thyroxine (T4) is intended for use as an internal standard for the quantification of Thyroxine (T4) by LC or GC-mass spectrometry.

If the number, nature and/or location of stable isotope label atoms (D, 15N, 13C) in this molecule don’t fit with your application, don’t hesitate to contact us to discuss your specific needs.
