How do I find a chemical labeled with stable isotopes on the Sigma-Aldrich website?
To find a labelled product on our website use the name of the chemical without any mention of labels (e.g. do not include 13C or D).Available labelled products will be listed in the matches for this search. For example if you search for 1,1,2,2-tetrachloroethane, amongst the matches you can find 1,1,2,2-tetrachloroethane-13C2 and 1,1,2,2-tetrachloroethane-d2.
