7-Methylguanine-15N5

7-Methylguanine-15N5 is a modified form of guanine, which is one of the four nucleotide bases that make up the genetic code of DNA. The addition of five nitrogen atoms to the molecule, four of which are stable isotopes of nitrogen, makes it useful for research purposes such as metabolic labeling and tracing studies. The chemical formula of 7-Methylguanine-15N5 is C6H6N5O, and its molecular weight is 170.15 g/mol. It is a white crystalline powder, which is soluble in water, ethanol, and dimethyl sulfoxide (DMSO). This modified form of guanine is primarily used in stable isotope labeling studies, where it is incorporated into DNA or RNA molecules. This allows researchers to track the metabolic fate of specific molecules or cells in biological systems. It is also used in other areas of research, such as drug development, where it can be used as a reference standard or as a tool for studying drug metabolism. 7-Methylguanine-15N5 is a relatively stable compound and is not known to be toxic or carcinogenic. However, as with any chemical compound, appropriate safety precautions should be taken when handling it. This includes wearing proper protective equipment, working in a well-ventilated area, and following all established safety protocols.
