Abstract
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—).
