The software is primarily designed to automate complex reactivity index calculations that would otherwise be labor-intensive. Key features include:

: Provides detailed insights into specific reactive sites within a molecule.

UCA-FUKUI is a specialized computational chemistry tool developed to streamline the study of chemical reactivity through the calculation of reactivity indices. It is widely used by researchers to determine how molecules will behave during nucleophilic, electrophilic, and radical attacks.

: Determines condensed indices for electrophilic, nucleophilic, and radical attacks.
