L-Liothyronine: Triiodothyronine Free Acid (T3)
L-Liothyronine is the free acid form of the L-isomer of triiodothyronine (T3), the biologically active thyroid hormone responsible for regulating metabolism, growth, and development. Unlike the sodium salt form, the free acid is primarily used as a pharmaceutical raw material and intermediate for the preparation of finished dosage forms and derivative salts.

Applications
L-Liothyronine free acid serves as a starting material for the preparation of liothyronine sodium tablets and injectable formulations. It is used in pharmaceutical development and compounding where conversion to the sodium salt is performed in-house. The free acid form may also be used in research applications studying thyroid hormone receptor binding and metabolism. Quality specifications typically include chiral purity confirmation to ensure the L-isomer, as the D-isomer is pharmacologically less active.
