Although slower than a diffusion-controlled reaction, chlorine transfer from the HOCl oxygen to the amino group nitrogen is a relatively rapid reaction, with half-lives of at most a few milliseconds at neutral pH and typical reagent concentrations. Direct analytical measurements of amino acid chlori ...
