Organic chemistry reaction mechanisms are validated through isotopic labeling and kinetics
Studies consistently show that isotopic labeling and kinetic analyses are fundamental experimental tools used to validate reaction pathways, intermediates, and mechanisms in organic and catalytic chemistry.
The claim states that organic chemistry reaction mechanisms are validated through isotopic labeling and kinetics. Multiple retrieved papers explicitly employ kinetic measurements and isotope labeling (e.g., 18O labeling, deuterium isotope effects) to elucidate and validate reaction pathways and intermediate species, directly supporting the claim. None of the papers refute it.

Isotope labeling experiments are used to demonstrate that the proton reservoir donates protons for the reaction mechanism.
