Description

3 3' 5-Triiodo-L-Thyronine Sodium Salt is the sodium salt form of the active thyroid hormone triiodothyronine (T3). This compound is of critical importance in biochemical research and pharmaceutical development due to its potent metabolic and regulatory functions. It is primarily required by research institutions, pharmaceutical companies, and diagnostic manufacturers for use in metabolic studies, hormone replacement therapy research, and as a key reference standard.

Application

• Pharmaceutical Reference Standard: Used as a primary standard for the quality control and assay development of thyroid hormone medications and supplements.
• Biochemical Research: Essential for in-vitro and in-vivo studies investigating thyroid hormone action, cellular metabolism, gene expression, and receptor binding.
• Diagnostic Reagent Manufacturing: A critical component in the production of immunoassay kits (e.g., ELISA, RIA) for the accurate measurement of T3 levels in clinical and veterinary diagnostics.
• Metabolic Pathway Analysis: Employed in research focused on understanding metabolic disorders, energy homeostasis, and the role of thyroid hormones in development.
• Cell Culture & Tissue Engineering: Used as a supplement in defined media for studies requiring thyroid hormone signaling in cultured cells or engineered tissues.
• Veterinary Pharmaceutical Development: Applied in the research and formulation of thyroid treatments for companion and agricultural animals.
