The present disclosure relates to a ferrocene-based compound having high selectivity for sulfide ion. The ferrocene-based compound is obtained by reacting a ferrocene starting material with one or more organic compound selected from a nitrile, a methyl ester and an ethyl ester, and a chemical sensor in solution state is prepared by mixing the compound with an organic solvent. The chemical sensor according to the present disclosure has high selectivity and sensitivity for sulfide ion even at low concentration and may be used as a chemical sensor for detecting hydrogen sulfide in solution state by allowing visual inspection of sulfide ion. In addition, the present disclosure provides a hydrogen sulfide detection kit including an airtight container including an opening/closing door and a detection material inlet, a detection unit which is provided inside the airtight container and composed of paper or fabric to which a ferrocene compound is adsorbed, and a basic reagent which is stored inside or outside the airtight container and generates sulfide ion from hydrogen sulfide. According to the present disclosure, hydrogen sulfide can be detected in real time by generating sulfide ion from hydrogen sulfide in gas or liquid state and visually inspecting the color change of the ferrocene compound of the detection kit.
