Levothyroxine sodium hydrate
3,3',5,5'-Tetraiodo-L-thyronine sodium saltm is the sodium salt of levothyroxine, a synthetic levoisomer of thyroxine (T4) that is similar to the endogenous hormone produced by the thyroid gland.

T3 also exhibits cardiostimulatory effects. Synonyms: Levothyroxine sodium monohydrate; L-Thyroxine sodium hydrate. Grade: ≥ 98% (HPLC). CAS No. 25416-65-3. Molecular formula: C15H10I4NNaO4.xH2O.
