Abstract

Nimustine hydrochloride systematic name: 4-amino-5-(N-(2-chloroethyl)-N-nitrosocarbamoylaminomethyl)-2-methylpyrimidin-1-ium chloride, C9H14ClN6O2+&\#183;Cl&\#18;, is a prodrug of CENU (chloroethylnitrosourea) and is used as a cytostatic agent in cancer therapy. Its crystal structure was determined from laboratory X-ray powder diffraction data. The protonation at an N atom of the pyrimidine ring was established by solid-state NMR spectroscopy.
