General description

13CH3OH is isotopically enriched form of methyl alcohol.

Application

Methyl-13C alcohol is an external reference for the assignment of polymer constitution using nuclear magnetic resonance spectroscopy. It is used to study the proton transfer processes, which offering possibilities for the quantitative mechanism studies of proton-related catalytic reactions. This isotope-enrich solvent is used to confirm the distribution and arrangement of metals from metal organic frame work (MOF) using host-guest interaction study. Also used as trideuteromethylation reagent for the synthesis of deuterated drugs.

Proton transfer (PT) processes in solid-liquid phases play central roles throughout chemistry, biology and materials science. Identification of PT routes deep into the realistic catalytic process is experimentally challenging, thus leaving a gap in our understanding. Here we demonstrate an

Optically pumped magnetometers (OPMs) based on alkali-atom vapors are ultra-sensitive devices for dc and low-frequency ac magnetic measurements. Here, in combination with fast-field-cycling hardware and high-resolution spectroscopic detection, we demonstrate applicability of OPMs in quantifying nuclear magnetic relaxation phenomena.

Utilising one-carbon substrates such as carbon dioxide, methane, and methanol is vital to address the current climate crisis. Methylotrophic metabolism enables growth and energy generation from methanol, providing an alternative to sugar fermentation. Saccharomyces cerevisiae is an important industrial microorganism
