It is an object of the present invention to provide a means for measuring a concentration of various components rapidly with high accuracy and high sensitivity. The present invention is to provide an oxidative chromogenic compound or salt thereof represented by the following chemical formula (1): wherein R1 and R2 are each independently a linear or branched alkyl group having 1 to 5 carbon atoms; R3, R4, R5, R6 and R7 are each independently a hydrogen atom, a carboxyl group or a sulfonic acid group, or salt thereof, provided that at least one of R3 to R7 is a carboxyl group or a sulfonic acid group, or salt thereof, and the others are hydrogen atoms, and the production method thereof, and the reagent composition and test instrument using the same.
