    Abstract: PURPOSE: A novel 4-£(alkylsulfanyl)methyl|-1,2-benzenediol derivative, its preparation method and a composition containing the derivative for an antioxidant, a whitening agent or a cholesterol controller are provided, to obtain the compound which suppresses the generation of melanin and controls the concentration of cholesterol by suppressing the oxidation of low density lipoprotein. CONSTITUTION: The 4-£(alkylsulfanyl)methyl|-1,2-benzenediol derivative is represented by the formula 1, wherein R is an alkyl group of C1-C10. The method comprises the step of reacting the 1,3-benzodioxol-5-yl-methanol of the formula 2 with the alkylthiol represented by R-SH in the presence of an acid, wherein R is an alkyl group of C1-C10. Preferably the acid is selected from the group consisting of AlCl3, FeBr3, FeCl3 and BBr3; and the reaction is performed in at least one solvent selected from the group consisting of dichloromethane, chloroform, acetonitrile, tetrahydrofuran and dimethyl formaldehyde.
