What can NMR do in an ADME laboratory?

The two primary tasks faced in an ADME study are

identification and quantification of metabolites.

NMR spectroscopy has been the definitive tool for

structural studies over many years. Modern probe

technology allows researchers to collect high quality

structural data on very small samples, while advances

in console design have opened the door to absolute

concentration measurements on any sample.

While Mass Spectrometry is the predominant

technique used for ADME investigations, NMR has a

critical role to play in this environment, too.

Quantitative NMR Spectroscopy - qNMR Why is NMR a valuable tool for quantitation?

In contrast to almost all other common quantitative techniques, the NMR

experiment is fundamentally quantitative. The response factor for any

given nuclei is 1.000, regardless of molecular structure or environment.

Historically, the limiting factor for using NMR for routine quantitative

studies has been poor reproducibility in the console hardware.

Compensating for this required an internal standard or injection of an

artificial reference signal. Both of these solutions are suboptimal.

Summary

• Agilent NMR systems are easy to use. By providing an array of

automated tools and utilities, VnmrJ allows you to focus on learning about your

samples rather than learning how to use the software.

• Sophisticated NMR techniques, such as band-selective

experiments, are available to any researcher. A powerful and

complete library of over 360 experiments can be used by anyone with just a few

mouse clicks.

• You can use NMR to measure the absolute concentration of

practically any sample. Agilent’s NMR systems provide the stability and

linearity needed to measure absolute concentration without the need for internal

standards or artificial reference signals.

• CRAFT provides automated Spectrum-to-Spreadsheet

deconvolution. Deconvolution of NMR spectra has reached reached the 21st

century.
