The present invention pertains to: an oxidation color developable compound that is represented by general formula (1), that has excellent solubility in water, and that is less affected by a substance coexisting in a sample; and an oxidation color development reagent using the oxidation color developable compound. In general formula (I), R1, R2, R3, and R4 each represent a straight-chain or branched alkyl group having 1-6 carbon atoms, X represents a hydrophilic functional group, and L represents —(CH2)j— (j represents an integer of 2-10), —(CH2CH2O)k— (k represents an integer of 1-10), or —(CH2)m—Z—(CH2)n— (m and n each independently represent an integer of 1-10, and Z represents —N+(CH3)2—, —CONH—, —NHCO—, —COO—, —OCO—, —NHCOO—, —OCONH—, —NHCONH—, and —(CH2NHCO)q—).
本发明涉及:一种由通式(1)表示的可氧化显色化合物,该化合物在
水中具有良好的溶解性,并且受样品中共存物质的影响较小;以及一种使用该可氧化显色化合物的氧化显色试剂。在通式(I)中,R1、R2、R3 和 R4 分别代表具有 1-6 个碳原子的直链或支链烷基,X 代表亲
水官能团,L 代表-(
CH2)j-(j 代表 2-10 的整数)、-( O)k-(k 代表 1-10 的整数),或-( )m-Z-( )n-(m 和 n 各自独立地代表 1-10 的整数,Z 代表-N+(
CH3)2-、-CONH-、-NHCO-、-COO-、-OCO-、-NHCOO-、-OCONH-、-NHCONH- 和-( NHCO)q-)。
