Our chemists are specialists in the synthesis of isotopically labelled Thyroxine standards for quantitative analysis. We are pleased to offer a range of Thyroxine standards including 13C labelled T2, T3, rev-T3, and T4.

We also offer the unlabelled native forms of the Thyroxines. These can be found in our All Individual Compounds subcategory or by entering a product name, CAS number or other keywords in the search field at the top of any page.

If you are unable to locate the standard or the format you require, please contact us with your requirements, we will be delighted to help.
