Methanol-d4

Description:
Methanol-d4, also known as deuterated methanol, is a stable isotopic variant of methanol where the hydrogen atoms are replaced by deuterium, a heavier isotope of hydrogen. Its chemical formula is CD3OD, and it is commonly used in various scientific applications, particularly in nuclear magnetic resonance (NMR) spectroscopy as a solvent due to its ability to provide a deuterium signal that does not interfere with the proton signals of organic compounds. Methanol-d4 is a colorless, volatile liquid with similar physical properties to regular methanol, including a low boiling point and high polarity, making it an effective solvent for a wide range of polar and nonpolar substances. The presence of deuterium alters its vibrational frequencies, which can be advantageous in studies involving molecular dynamics and interactions. Additionally, methanol-d4 is utilized in research involving isotopic labeling, allowing scientists to trace the pathways of chemical reactions and study metabolic processes in biological systems. Its CAS number is 811-98-3, which uniquely identifies this specific isotopologue in chemical databases.
