4-Amino-N-(6-methoxypyrimidin-4-yl)benzenesulfonamide (cas: 1220-83-3) belongs to pyrimidine derivatives. The aromatic compound pyrimidine, and its derivatives, are ubiquitous in nature. They are found in nucleic acids, vitamins, amino acids, antibiotics, alkaloids, and a variety of toxins. For example, the neurotoxin tetrodotoxin is a pyrimidine derivative. It is found in a number of species including the Japanese puffer fish, the blue-ringed octopus, and the orange-bellied newt. Tetrodotoxin prevents the transmission of nerve signals and can result in paralysis and death.Computed Properties of C11H12N4O3S
Evaluating sewer exfiltration in groundwater by pharmaceutical tracers after the 2016 Kumamoto earthquakes, Japan was written by Kobayashi, Jun;Kuroda, Keisuke;Miyamoto, Chinatsu;Uchiyama, Yukiko;Sankoda, Kenshi;Nakajima, Daisuke.

In Apr. 2016, a series of earthquakes (M 7.3 on the Japan Meteorol. Agency scale) occurred in Kumamoto, Japan causing serious damage to underground sewerage networks. In this study, we evaluated sewer exfiltration in groundwater in the Kumamoto area after the earthquakes by using multiple tracers. We used 14 pharmaceuticals, including carbamazepine and crotamiton, and anthropogenic Gd as tracers, and we measured concentrations of these tracers from Sept. 2016 to Nov. 2017 seasonally. The detection frequency of caffeine, carbamazepine, crotamiton, ibuprofen, and anthropogenic Gd ranged from 29% to 45%, and the concentrations of the pharmaceuticals in the groundwater were lower than those in previous studies. The median of all pharmaceutical concentrations did not decrease, whereas the median of the sum of crotamiton and carbamazepine concentrations, which are quant. sewage markers, decreased with time. The sewer exfiltration rates in Sept. 2016 estimated using carbamazepine, crotamiton, and anthropogenic Gd were 0.59 闁?0.27%, 0.66 闁?0.47%, and 0.11 闁?0.18% of sewage dry weather flow, resp., indicating that the effect of the earthquakes on sewer exfiltration was small, probably because the damaged sewers were quickly repaired. This study demonstrated that a multiple-tracer approach is useful for evaluating sewer exfiltration after major earthquakes. In the experiment, the researchers used many compounds, for example, 4-Amino-N-(6-methoxypyrimidin-4-yl)benzenesulfonamide (cas: 1220-83-3Computed Properties of C11H12N4O3S).
