And the article was included in Shizuoka-ken Kankyo Eisei Kagaku Kenkyusho Hokoku in 2009.Computed Properties of C5H6N2O This article mentions the following:
Due to the higher frequency of use or incidents of violations in the past, a method of collective anal. of residual veterinary drugs which were highly required to analyze in the inspection was investigated. Using LC/MS/MS in which anal. of high sensitivity and high selectivity is possible, the measurement conditions were established for 73 items. As regards the pre-processing method, the acetonitrile-methanol (7:3) is used in the extraction solvent and study regarding the extraction of veterinary drugs with wide range of phys. properties was conducted. As a result, the recovery rate in all studied items was 70-120% and among 73 items 53 items were below RSD 20%. This method is thought to be quick, simple and collective anal. method for the residual veterinary drugs with a wide range of phys. properties. In the experiment, the researchers used many compounds, for example, 3-Methoxypyridazine (cas: 19064-65-4Computed Properties of C5H6N2O).
3-Methoxypyridazine (cas: 19064-65-4) belongs to pyridazine derivatives. Pyridazine and phthalazine have quite different spectroscopic properties compared with their isomers, pyrazine and quinoxaline. The activity depends upon the changes of substituted groups in the pyridazine ring system resulting in different biological activities. In addition, the natural pyrimidine bases uracil, thymine, and cytosine, which are constituents of the nucleic acids, are found to be the most important naturally occurring diazines.Computed Properties of C5H6N2O
