Properties and data of the isotope 11 C. Carbon-11 or 11 C is a radioactive isotope of mass 11 of the element carbon, which has a half-life of about 20, 5 minutes decays to boron-11. The atomic nucleus of the nuclide is made up of 5 neutrons and the 6 element-specific protons.
Carbon-11 or 11 C is a radioactive isotope of carbon that decays to boron-11. This decay mainly occurs due to positron emission, with around 0.19–0.23% of decays instead occurring by electron capture. [6] [7] It has a half-life of 20.3402(53) min. 11 C → 11 B + e + + ν e + 0.96 MeV 11 C + e − → 11 B + ν e + 1.98 MeV
27 maj 2024 · The pattern of lines in the mass spectrum of an organic compound tells you something quite different from the pattern of lines in the mass spectrum of an element. With an element, each line represents a different isotope of that element.

26 sty 2021 · This review focuses on the carbon-11 radiochemistry and various target-specific PET molecular imaging agents used in tumor, heart, brain, and neuroinflammatory disease imaging along with its associated pathology.
3 kwi 2019 · Carbon-11 is an accelerator-produced, positron-emitting radionuclide. Its physical half-life of 20.4 min is sufficiently long to allow for multistep syntheses while short enough to enable multiple PET scans of the same individual on the same day.
25 lut 2017 · This review summarizes some of the most recent and promising strategies to obtain carbon-11 labeled products. In the past two decades, and well before this, efforts have brought to bear an impressive range of methods for 11 C-radiochemistry. However, there are still issues to be addressed.
