Determination of hydrazine in pharmaceuticals

Determination of hydrazine in pharmaceuticals. IV: Hydrazine and benzylhydrazine in isocarboxazid. Lovering, E. G.; Matsui, F.; Robertson, D.; Curran, N. M. (Bur. Drug Res., Health Welfare Canada, Ottawa, ON K1A 0L2, Can.). J. Pharm. Sci., 74(1), 105-7 (English) 1985. CODEN: JPMSAE. ISSN: 0022-3549. DOCUMENT TYPE: Journal CA Section: 64 (Pharmaceutical Analysis) A gas chromatog. procedure for the simultaneous detn. of hydrazine [302-01-2] and benzylhydrazine [555-96-4] in isocarboxazide [59-63-2] bulk and tablet formulations is based on the reaction of benzoyltrifluoroacetone [326-06-7] with hydrazine and benzylhydrazine to form the corresponding pyrazole derivs. The min. detectable amts. of hydrazine and benzylhydrazine in isocarboxazide are 0.002 and 0.2%, resp.

Structure-energy correlations for hydrazine and 2-tetrazene oxidation potentials

Structure-energy correlations for hydrazine and 2-tetrazene oxidation potentials. Nelsen, S. F.; Peacock, V. J. (Dep. Chem., Univ. Wisconsin, Madison, Wis., USA). J. 555-96-4 are also occured in this study. Am. Chem. Soc., 99(25), 8354-5 (English) 1977. CODEN: JACSAT. DOCUMENT TYPE: Journal CA Section: 72 (Electrochemistry) Section cross-reference(s): 22 Alkyl groups show a detectable difference in their ability to stabilize dialkylamino radical cations relative to the neutral compds. in soln. and Taft s consts. give a useful linear correlation with electronic effects. Benzyl was included in detg. the s value relation to the electronic effects since it has the opp. sign for s as satd. alkyl groups. The E° values were detd. for substituted hydrazines and 2-tetrazenes in MeCN and plots of E° vs. Ss were made for some tetradzines. The E° values for tetra-n-alkylhydrazines are detectably influenced by steric differences but the electronic effects of changing alkyl group size is somewhat greater. .
