To provide an iridium that has an N-hydroxysuccinimide ester group, which responds to a wavelength region called a biological window and is a site of binding to a biological substance.SOLUTION: Provided is a compound that is represented by the following formula (1). [In the formula (1), a ring A and a ring C, each independently represent a benzene ring which may have a substituent. A ring B and a ring D, each independently represent any one of a pyridine ring, a pyrazine ring, a pyrimidine ring, an imidazole ring, an oxazole ring, and a thiazole ring, each of which may have a substituent. X1 represents a nitrogen atom or CR2.].SELECTED DRAWING: None 【課題】本発明は、生体の窓と呼ばれる波長域に対応し、生体物質への結合部位であるＮ－ヒドロキシスクシンイミドエステル基を有するイリジウムを提供するものである。【解決手段】下記式（１）で表される化合物。TIFF2022081719000041.tif50154［式（１）中、環Ａ、環Ｃは、各々独立に置換基を有していても良いベンゼン環を表す。環Ｂ、環Ｄは、各々独立に置換基を有していても良いピリジン環、ピラジン環、ピリミジン環、イミダゾール環、オキサゾール環、チアゾール環のいずれかを表す。Ｘ１は、窒素原子またはＣＲ２を表す。］【選択図】なし
