PROBLEM TO BE SOLVED: To provide a new compound for producing calibration curves for sulfur and main halogens (F, Cl, Br and I) at the same time. SOLUTION: The invention provides a new compound synthesized by condensing a compound selected from halogenated aniline compounds with a compound selected from halogenated benzenesulfonyl compounds in an alkaline solvent and containing four kinds of halogens (F, Cl, Br and I) and sulfur (S), especially the above compound having a structure of N-(2'-iodo-4-bromophenyl)-3-chloro-4-fluorobenzenesulfonamide. The new compound for producing calibration curves can be produced easily in high yield and purity, and the analysis time can be remarkably shortened by using the compound in a package autoanalysis of halogen-sulfur in a halogen-sulfur microanalyzer.
