Ronidazole-d3 (CAS 1015855-87-4)

TEST CONDITIONS

Purity (HPLC): Column (Luna Phenyl-Hexyl, 250 x 4.6mm, 5 um), Solvent (Acetonitrile : Water, 70 : 30), Detection Wavelegth (305 nm), Retention Time (4.93 min.)Isotopic Enrichment by 1H-NMR: 500 MHz, DMSO-D6, Delta = 5.10 (s, 2H), 6.76 (br, 2H), 8.06 (s, 1H) ppmElemental Analyses of Carbon and Deuterium: The detector of the elemental analyzer is measuring the quantity of hydrogen and deuterium together. It cannot differentiate between the two isotopes (in contrast to other commercial detectors, detecting with gas chromatography). If all hydrogen isotopes in molecule would be deuterium we would find only half of the theoretical (calc.) amount. It means that the theoretical amount of your substance is 3.97 %, composed of 2.48 % hydrogen and 1.49% hydrogen (half of 2.97% calc. deuterium, because of double mass compared to hydrogen). In the case of NM010 we have found a value of 4.10 % H(+D), so the amount correlates to the theoretical calculated amount (all values have to be within the error margin of +-0.3%).
