CAS 7789-20-0: Água-d2
Descrição:
Água-d2, também conhecido como água deuterada ou água pesada, é uma forma de água onde os átomos de hidrogênio são substituídos por deutério, um isótopo estável do hidrogênio. Sua fórmula química é D2O, indicando que contém dois átomos de deutério em vez dos dois átomos de hidrogênio habituais encontrados na água comum (H2O). Essa substituição resulta em várias características únicas. A água deuterada tem uma densidade maior do que a água comum, o que pode afetar suas propriedades físicas, como pontos de ebulição e congelamento, tornando-os ligeiramente mais altos do que os da água ordinária. Além disso, a água pesada exibe diferentes propriedades de ressonância magnética nuclear (RMN), tornando-a útil em várias aplicações científicas, incluindo espectroscopia de RMN e como moderador de nêutrons em reatores nucleares. Embora não seja tóxica em pequenas quantidades, a água pesada pode ser prejudicial em grandes quantidades devido aos seus efeitos nos processos biológicos. Seu número CAS, 7789-20-0, é usado para identificação em bancos de dados químicos e contextos regulatórios.

CAS:Deuterium oxide is used in nuclear magnetic resonance spectroscopy (NMR). It is also useful in the identification of labile hydrogens. As a source of deuterium, it is utilized for preparing specifically labeled isotopologs of organic compounds. It is often used as a substitute for water in the analysis of proteins in solution by using fourier transform infrared spectroscopy (FTIR). It finds application in certain types of nuclear reactors and in tritium production. This Thermo Scientific Chemicals brand product was originally part of the Alfa Aesar product portfolio.
