Preguntas frecuentes

How do I choose between 2H, 13C, 15N, and 18O labeling?
Deuterium (2H) is most common for NMR and metabolic studies due to lower cost. 13C provides minimal mass shift for MS quantitation. 15N is essential for protein dynamics and metabolic flux. 18O is used for proteomics and water-tracking studies.
What isotopic enrichment levels are available?
Typical enrichments are 98 atom% for deuterium, 99 atom% for 13C and 15N, and up to 99.9% for specialty grades. Higher enrichment reduces interference in quantitative MS but costs more — match the level to your sensitivity needs.
What specifications matter for isotope-labeled compounds?
Isotopic enrichment (atom%), chemical purity, position of label, isotopologue purity (single vs. multi-labeled), storage stability, and pack size. Always check for unlabeled (natural abundance) contamination in quantitative work.
Are deuterated NMR solvents available?
Yes. The Stable Isotopes category includes CDCl3, DMSO-d6, D2O, CD3OD, and other common NMR solvents at typical 99.8–99.9% D enrichment with low water content options.
