General information

NMR Spectroscopy

Deuterated compounds are mainly used in NMR spectroscopy to characterise organic structures. This has the advantage of virtually eliminating solvent signals. In addition, acidic protons can be exchanged for deuterium to make it easier to assign the signals.

Application examples:

  • Routine tasks such as structure determination and identity verification in research and development laboratories
  • Elucidation of reaction mechanisms and metabolisms
  • For GC-MS or LC-MS as internal standards
Properties:
  • High degree of deuteration
  • High purity of the starting compound
  • Defined water content
  • Filled under protective gas (nitrogen), except for compounds containing TMS


NMR Chemical Shifts of Common Solvents as Trace Impurities

These tables present the NMR shifts of commonly used solvents and impurities in organic synthesis and workup protocols measured in the 7 most frequently used deuterated solvents.

To simplify the identification of these solvents in NMR spectra and facilitate their adoption into chemical processes, we have compiled 1H and 13C NMR data for common laboratory solvents.

Derivatisation Reagents for GC

Derivatisation reagents are used mainly in gas chromatography when adequate volatility or stability of the substances to be separated is required. Detection sensitivity can also be increased through derivatisation.

Our range of derivatisation reagents is ideal for acylation, alkylation and silylation of reagents.
