Description
Liothyronine Sodium Product Overview
Liothyronine sodium (C15H11I3NNaO4) is the sodium salt of L-triiodothyronine (T3). It is a light tan to off-white powder that is very slightly soluble in water. It is the biologically active form of thyroid hormone, while Levothyroxine Sodium (T4) is converted to T3 in the body.
Pharmaceutical companies use it in tablets and injections, and veterinary producers in some products for animals. Daily doses are only a few micrograms, so content uniformity and stability are critical quality factors.
Zyntex supplies liothyronine sodium from qualified producers with lot-specific documentation, only to licensed pharmaceutical and veterinary companies.
