Labeling of unnatural amino acids with technetium-99m and tissue distribution of the labeled products in mice was written by Tamemasa, Osamu;Goto, Rensuke;Takeda, Atsushi. And the article was included in Radioisotopes in 1981.HPLC of Formula: 32595-59-8 This article mentions the following:
99mTc-labeled unnatural amino acids were prepared by conventional methods and their distribution in mice organs after i.v. injection was determined Most of the labeled amino acids were found in the kidney, whereas only small amounts in the pancreas. 99mTc-labeled 4-azaleucine and -azaserine showed the highest distribution in the liver (19.3 and 17.1% dose/g wet weight, resp.). A low distribution in the stomach was shown only by a few of the labeled amino acids. In the experiment, the researchers used many compounds, for example, 2-Amino-3-hydroxy-3-(thiophen-2-yl)propanoic acid (cas: 32595-59-8HPLC of Formula: 32595-59-8).
2-Amino-3-hydroxy-3-(thiophen-2-yl)propanoic acid (cas: 32595-59-8) belongs to benzothiophene derivatives. Benzothiophenes are valuable heterocycles that are widely used in medicines, agrochemicals, and materials science. It is also used in the manufacturing of dyes such as thioindigo.HPLC of Formula: 32595-59-8
