Title: Labelled compounds
Post by: Cantacoxinha on April 06, 2017, 05:19:15 AM

Can you recommend some companies specialized in producing and selling isotopically labelled compounds - not NMR solvents, but fine chemicals mostly bearing ²H, ¹³C and ³⁴S? I've been checking a couple of "mainstream" companies, but the choice is kinda scarce.. I don't have Reaxys/SciFinder available, unfortunately.

Cambridge Isotope Labs has been a supplier in the past.

Our lab uses Cambridge. We've not had any problems with them. Previously we used another brand (it's been several years since, so I forget the name), but we had a problem with some sort of grease contaminant.
