Clinical Stable IsotopesClinical Stable Isotopes

As the use of advanced techniques such as mass spectrometry continues to increase in the field of Clinical analyis we are pleased to offer many isotopically labelled compounds for use as internal standards.

This range includes Catecholamines, Biogenic amines, Immunosuppresants, Thiopurines and Xanthines including Caffiene and metabolites. Please also see our other subcategories for stable isotopes of Carnitines, Thyroxines and Toxicology reference materials.

Please see the reference materials listed below or enter a product code, CAS number, description or other keywords in the Search field below.

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

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