Chloroform-D stabilized

Chloroform-D stabilized is a deuterated form of chloroform, a colorless and volatile liquid with a sweet odor. It is commonly used in analytical chemistry and NMR spectroscopy as a solvent and a reference standard. The "D" in Chloroform-D stands for deuterium, an isotope of hydrogen that has a neutron in its nucleus, making it heavier than regular hydrogen. The presence of deuterium in Chloroform-D results in a different chemical shift in NMR spectroscopy, which allows for better resolution and identification of compounds. Chloroform-D stabilized is often preferred over regular chloroform because it is less prone to decomposition and evaporation, which can affect the accuracy of NMR measurements. It is also more stable and less reactive, making it a safer solvent to work with in the laboratory. However, it is important to note that Chloroform-D is still a hazardous substance and should be handled with caution. In terms of chemical information, Chloroform-D has a molecular formula of CDCl3 and a molecular weight of 120.38 g/mol. It has a boiling point of 61.2°C and a density of 1.443 g/mL. The stabilization of Chloroform-D is achieved by adding a small amount of ethanol or methanol to prevent the formation of acid and other impurities. Overall, Chloroform-D stabilized is a valuable tool in analytical chemistry and NMR spectroscopy for its accuracy and stability.
