What is CARBON-13C?
Description
Methane-13C, also known as carbon-13C. Methane-13C-labeled methacetin breath test is a newly developed method for the detection of liver function, which is safe, simple, specific and quantitative.
The Uses of CARBON-13C
Carbon-13C is a stable isotope. Due to the characteristics of high safety, simplicity, non-invasiveness, strong sensitivity and specificity, it has gradually replaced radioactive reagents and played an increasingly important role in the diagnosis of diseases in clinical medicine, which is favored by the medical industry at home and abroad.
Definition
ChEBI: Carbon-13 atom is a carbon atom.
Synthesis
Add iodomethane-13C, paracetamol, potassium carbonate and acetonitrile rapidly under nitrogen gas to obtain Carbon-13C.
