Thyroxine hydrochloride-¹³C₆  (Synonyms: L-甲状腺素 盐酸盐-¹³C₆; Levothyroxine-¹³C₆; T4-¹³C₆)

Thyroxine hydrochloride-¹³C₆ is the ¹³C-labeled L-Thyroxine. L-Thyroxine (Levothyroxine; T4) is a synthetic hormone for the research of hypothyroidism. DIO enzymes convert biologically active thyroid hormone (Triiodothyronine,T3) from L-Thyroxine (T4)[1].

Stable heavy isotopes of hydrogen, carbon, and other elements have been incorporated into drug molecules, largely as tracers for quantitation during the drug development process. Deuteration has gained attention because of its potential to affect the pharmacokinetic and metabolic profiles of drugs^[1].

MCE has not independently confirmed the accuracy of these methods. They are for reference only.
