1H NMR detection of small molecules in human urine with a deep cavitand synthetic receptor

Analyst. 2013 Feb 21;138(4):1008-10. doi: 10.1039/c2an36635e.

Abstract

A water-soluble deep cavitand recognized alkylammonium salts, including the drug amantadine hydrochloride, in spiked samples of human urine. The signals of the guests are detected by (1)H NMR upfield of 0 ppm and so occur in a spectroscopic window that is outside of the normal region and distinct from the signals of the biofluid components.
