What is Sodium levothyroxine pentahydrate?
What are the applications of Application
L-Thyroxine Sodium Salt Pentahydrate is a thyroid hormone
Hazard
A reproductive hazard.
Biochem/physiol Actions
L-Thyroxine (T4) and triiodo-L-thyronine (T3) are iodine-containing hormones produced from thyroglobulin in the thyroid follicular cells. The stimulation of metabolic rate and regulation of growth and development by these hormones appear to be due to their effects on DNA transcription and thus, protein synthesis.
Purification Methods
Crystallise the sodium salt from absolute EtOH and dry it for 8hours at 30o/1mm. [Canepa Acta Cryst 4 283 1951, Beilstein 14 II 378, 14 III 1566, 14 IV 2374.]
