About isotope-labelled compounds
Isotope-labelled compounds contain stable isotopes such as deuterium (2H), carbon-13, nitrogen-15, oxygen-18 or sulfur-34 in place of the common isotopes. The group covers deuterated NMR solvents such as chloroform-d, DMSO-d6, methanol-d4 and deuterium oxide, labelled internal standards for mass spectrometry, labelled amino acids, sugars and nutrients for metabolic and proteomics research, heavy water, and labelled building blocks for synthesis. Radiolabelled compounds are handled separately because they need licences.

Labelled internal standards make quantitative mass spectrometry accurate in drug development, clinical testing, food safety and environmental analysis. NMR solvents are used daily in every chemistry lab, and labelled nutrients support research on metabolism and protein structure.
Ask for isotopic enrichment in atom percent, chemical purity, the labelling positions, the isotopic distribution for mass spectrometry standards, water content for NMR solvents, and storage conditions. Many labelled standards are custom synthesised in milligram amounts, so lead times can be long. Deuterated drugs and some heavy water quantities may face export controls.
