Barlin, Gordon B. published the artcile< Methylation of aminopyridazines>, HPLC of Formula: 20744-39-2, the main research area is methylation aminopyridazine; pyridazine amino methylation; aminopyridazinium iodide UV NMR; acidity aminopyridazine.
Treatment of 3- and 4-amino- and 3,5-diaminopyridazine with MeI in MeOH gave mixtures of the corresponding 1- and 2-methyl iodides whereas 3,4-, 3,6-, and 4,5-diaminopyridazines gave only one methiodide, in the first case identified as 3,4-diamino-1-methylpyridazinium iodide. No ammonio compounds were detected. The ionization constants and uv and PMR spectra of the pyridazines, their methiodides, and related compounds were determined and discussed.
Journal of the Chemical Society, Perkin Transactions 1: Organic and Bio-Organic Chemistry (1972-1999) published new progress about Acidity. 20744-39-2 belongs to class pyridazine, and the molecular formula is C4H5N3, HPLC of Formula: 20744-39-2.
