Synthetic Route of 19064-67-6, Chemistry is the science of change. But why do chemical reactions take place? Why do chemicals react with each other? The answer is in thermodynamics and kinetics.In a document type is Article, and a compound is mentioned, 19064-67-6, 6-Chloro-3-hydroxypyridazine, introducing its new discovery.

A mild, easy-to-perform, and versatile method for the formation of aminochlorodiazines from reaction of several types of dichlorodiazines (i.e., pyridazines, pyrimidines, and pyrazines) with primary or secondary amines in ethanol in the presence of triethylamine as a base, is described. The methodology is general and efficient despite noticeable difference in reactivity between diazines. While dichloropyridazine and dichloropyrazine require several hours of heating at reflux for the reaction to proceed, dichloropyrimidines reach completion within minutes at room temperature.

Chemistry is traditionally divided into organic and inorganic chemistry. Safety of Pyridazin-4-amine, The former is the study of compounds containing at least one carbon-hydrogen bonds.In a patent，Which mentioned a new discovery about 20744-39-2

The pK values for a series of aminoazines and acetylazines containing one, two, or three aza groups in the ring were determined in dimethyl sulfoxide.There is a good linear correlation between pK values of the investigated NH and CH acids.The acidifying effects (DeltapK) of the aza groups at positions 2, 3, or 4 in relation to the side chain were determined and had values of 3.1, 2.4, and 4.5 logarithmic units in the aminoazines and 3.5, 2.9 and 4.8 logarithmic units respectively in the acetylazines.Except in the case of two ortho-located aza groups the effects are additive.Compared with dimethyl sulfoxide water has a differentiating effect on the acidity of the aminoazines, and this is explained by the formation of hydrogen bonds between the molecules of the proton-donating solvent and the aza groups of the anions of the aminoazines.

A series of A-ring pyrrole compounds of duocarmycin bearing 4′-methoxy- beta-heteroarylacryloyl groups were synthesized and evaluated for in vitro anticellular activity against HeLa S3 cells and in vivo antitumor activity against murine sarcoma 180 in mice. Most of the 4′-methoxy-beta- heteroarylacrylates displayed in vitro anticellular activity equivalent to that of 4′-methoxy-cinnamates. Among the 8-O-[(N-methylpiperazinyl)carbonyl] derivatives of 4′-methoxy-beta-heteroarylacrylates, compound 15b having a (4- methoxy-3,5-pyrimidinyl)acryloyl as segment-B (Seg-B) showed remarkably potent in vivo antitumor activity and low peripheral blood toxicity compared with the A-ring pyrrole derivatives having the trimethoxyindole skeleton in Seg-B, which were equal to 8-O-[(N-methylpiperazinyl)carbonyl] derivatives of 4′-methoxycinnamates. Moreover, these 8-O-[(N-methylpiperazinyl)carbonyl] derivatives of 4′-methoxy-beta-heteroarylacrylates had high aqueous solubility.
