Publikováno v: Journal of Molecular Structure: THEOCHEM. 104:179-189

The crystal and molecular structure of (3-cyano-4,5-dimethyl pyrrol-2-yl) oxamic acid ethyl ester has been determined by X-ray diffraction techniques. The clear monoclinic crystals, space group P 2 1 / c , were found to contain four molecules in a un

Publikováno v: Analytical Letters. 7:243-255

A gas chromatographic-mass spectrometric (GC-MS) method for measuring dopamine levels in brain tissue has been developed. Deuterated dopamine was prepared by exchange of the aromatic hydrogens with deuterium. The method involves adding a known amount
