Triiodothyronine

Triiodothyronine (T3) is the biologically active thyroid-hormone compound, supplied by Nustras as a high-purity material for pharmaceutical manufacturing, compounding and research applications. T3 is the free acid; its sodium salt is liothyronine sodium. It is the more potent of the two principal thyroid hormones, the other being thyroxine, also known as tetraiodothyronine or T4.

The material is used by licensed pharmaceutical manufacturers, compounding pharmacies and research laboratories as an active pharmaceutical ingredient, reference standard and research chemical. It is not a dietary-supplement or food ingredient and is supplied only to qualified, licensed buyers for lawful use, with no therapeutic claims made.

Triiodothyronine carries CAS 6893-02-3, the molecular formula C15H12I3NO4 and a molecular weight of 650.97. Purity and assay are determined by HPLC to a pharmacopoeial or client specification, confirmed on each lot's certificate of analysis. The related compound thyroxine (T4 / tetraiodothyronine, levothyroxine, CAS 51-48-9) can be sourced on request.

Nustras supplies triiodothyronine in controlled, documented pack sizes against a signed specification and the appropriate licensing, with a certificate of analysis and safety data sheet on every lot, to qualified buyers internationally subject to all applicable controls. Triiodothyronine and liothyronine are prescription drug substances whose import, handling and sale are regulated; Nustras supplies the material only to buyers holding the appropriate licences and establishment registration.
