United States Pharmacopeia (USP) Reference Standard. Group: Pharmacopeia & metrological institutes standardseuropean pharmacopoeia (ph. eur.)pharmacopoeial standards. Alternative Names: Levothyroxine sodium, Sodium (2S)-2-amino-3-[4-(4-hydroxy-3,5-diiodophenoxy)-3,5-diiodophenyl]propanoate.
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. In peripheral tissues, levothyroxine is deiodinated by 5'-deiodinase to form triiodothyronine (T3). T3 enters the cell and binds to nuclear thyroid hormone receptors, the activated hormone-receptor complex in turn triggers gene expression and produces proteins required in the regulation of cellular respiration, thermogenesis, cellular growth and differentiation, and the metabolism of proteins, carbohydrates and lipids. 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. Mole weight: 798.85 (anhydrous basis).
Levulinic acid
Levulinic acid is a precursor for the synthesis of biofuels, such as ethyl levulinate. Levulinic acid is also a 5-keto-pentanoic acid.
