The purpose of the present invention is to provide: a novel compound for measuring cytotoxicity or cellular proliferative potential accurately, simply, and rapidly at high reproducibility; and a method for measuring cytotoxicity or cellular proliferative potential using this compound. The present invention pertains to a compound represented by formula (I): (in the formula, R 1 represents a substituent, R 2 and R 3 each represent an optionally substituted hydrocarbon group or an optionally substituted heterocyclic group, Y represents a substituent, m represents an integer of 0-3, Z represents a single bond, -O-, -S-, -SO-, -SO 2 -, or -NR 4 - (R 4 represents a hydrogen atom or substituent), and A represents an optionally substituted C 1-6 alkylene group), or a salt thereof. |
