Used in pharmaceutical research as a key intermediate in the synthesis of thyroid hormone receptor modulators. Its structural features, including the iodinated aromatic ring and chiral centers, make it valuable for developing compounds that target metabolic and endocrine disorders. The cyclopropyl and ester groups enhance binding selectivity and metabolic stability in drug candidates. It is also employed in structure-activity relationship (SAR) studies to optimize potency and pharmacokinetic properties of thyroid-related therapeutics.
