•An ignition delay predictive method was validated for n-dodecane using 5 mechanisms.•The method accuracy and variability depends on the species that acts as chain carrier.•Hydroperoxyl radical is a good tracer for cool flames.•Hydrogen peroxide is a good tracer for the high-temperature ignition sta...
