The chlorine atom is active and can participate in the nucleophilic substitution reaction. In the case of nucleophiles, chlorine atoms are easily replaced to form new derivatives. If the reaction with nucleophiles containing hydroxyl groups and amino groups, chlorine atoms may be replaced by hydroxyl groups and amino groups, providing a way for the synthesis of various benzimidazole derivatives.

4-Fluorobenzyl has high electronegativity of fluorine atoms, which makes the benzyl electron cloud biased towards fluorine atoms and affects the reactivity of benzyl groups. This group can enhance the lipid solubility of the compound, or affect its absorption, distribution, metabolism and excretion in vivo.

In terms of redox, if the compound encounters strong oxidants, the benzimidazole ring or the benzyl part may be oxidized; in the case of strong reducing agents, some unsaturated bonds may be reduced. However, the specific redox behavior depends on the reaction conditions and the reagents used.

In terms of stability, the compound is relatively stable under normal conditions. However, extreme conditions such as high temperature, strong acid, strong base or light, or their structure changes, trigger decomposition or other chemical reactions.
