CAS 7789-20-0: Acqua-d2
Descrizione:
Acqua-d2, noto anche come acqua deuterata o acqua pesante, è una forma di acqua in cui gli atomi di idrogeno sono sostituiti dal deuterio, un isotopo stabile dell'idrogeno. La sua formula chimica è D2O, che indica che contiene due atomi di deuterio invece dei due atomi di idrogeno abituali presenti nell'acqua normale (H2O). Questa sostituzione porta a diverse caratteristiche uniche. L'acqua deuterata ha una densità maggiore rispetto all'acqua normale, il che può influenzare le sue proprietà fisiche, come i punti di ebollizione e congelamento, rendendoli leggermente più elevati rispetto a quelli dell'acqua ordinaria. Inoltre, l'acqua pesante presenta diverse proprietà di risonanza magnetica nucleare (RMN), rendendola utile in varie applicazioni scientifiche, tra cui la spettroscopia RMN e come moderatore di neutroni nei reattori nucleari. Sebbene non sia tossica in piccole quantità, l'acqua pesante può essere dannosa in grandi quantità a causa dei suoi effetti sui processi biologici. Il suo numero CAS, 7789-20-0, è utilizzato per l'identificazione in database chimici e contesti normativi.

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.
