CAS 7789-20-0: Water-d2
Description:Water-d2, also known as deuterated water or heavy water, is a form of water where the hydrogen atoms are replaced by deuterium, a stable isotope of hydrogen. Its chemical formula is D2O, indicating that it contains two deuterium atoms instead of the usual two hydrogen atoms found in regular water (H2O). This substitution results in several unique characteristics. Deuterated water has a higher density than regular water, which can affect its physical properties, such as boiling and freezing points, making them slightly higher than those of ordinary water. Additionally, heavy water exhibits different nuclear magnetic resonance (NMR) properties, making it useful in various scientific applications, including NMR spectroscopy and as a neutron moderator in nuclear reactors. While it is not toxic in small quantities, heavy water can be harmful in large amounts due to its effects on biological processes. Its CAS number, 7789-20-0, is used for identification in chemical databases and regulatory contexts.
