Abstract
A reduced coenzyme Q10 derivative represented by formula (1), wherein R1 and R2 are each independently H or an alkoxycarbonyl group represented by formula (2), and at least one of them is an alkoxycarbonyl group represented by the formula (2); in the formula (2), R3 is an optionally substituted linear, branched, or cyclic alkyl group having 1 to 20 carbon atoms, an optionally substituted aryl group having 6 to 20 carbon atoms, or an optionally substituted heteroaryl group having 4 to 20 carbon atoms, and when R3 is a group substituted with polyethylene glycol, the molecular weight of the polyethylene glycol is not more than 300.
