Abstract

An object of the present invention is to provide a skin sensitization measuring reagent, a method for measuring skin sensitization, and a compound that allow the sensitization of a test substance to be measured using a single reagent. According to the present invention, there is provided a skin sensitization measuring reagent including, as a main measuring agent, an organic compound having at least one thiol group derived from an amino acid and at least one amino group derived from a side chain of an amino acid. The organic compound has an absorption spectrum in an ultraviolet, visible, or near-infrared region and has a molar absorption coefficient of 100 L/mol·cm or more and 500,000 L/mol·cm or less at a maximal absorption wavelength.
