Used primarily as a key intermediate in the synthesis of pharmaceutical compounds, particularly in the development of thyroid hormone receptor agonists. It plays an essential role in the preparation of drugs targeting metabolic and liver-related disorders, such as non-alcoholic steatohepatitis (NASH) and dyslipidemia. Its structure allows for selective binding and modulation of thyroid hormone receptors, contributing to improved metabolic activity with reduced cardiac side effects. Commonly utilized in medicinal chemistry research for optimizing drug candidates with enhanced potency and selectivity.
