CAS 811-98-3 — Methanol-d4

Methanol-d4 is a deuterated analog of methanol (CD3OD), widely used as a solvent and internal standard in NMR spectroscopy, stable isotope labeling studies, and deuterium exchange reactions. It replaces hydrogen atoms with deuterium, enabling precise isotopic analysis and improved signal resolution in analytical applications. This chemical has a CAS number of 811-98-3, a molecular weight of 36.07 g/mol, and requires ambient storage. It carries a **Danger** signal word due to its flammability and toxicity. Molekula supplies Methanol-d4 from research to bulk quantities with full documentation and ISO 9001:2015 traceability.
