Benzoic acid derivatives of the formula: <IMAGE> wherein n is an integer of 0 to 2; R1 to R3 which may be the same or different each represents a hydrogen atom, a halogen atom, a lower alkyl group, a lower alkoxy group or nitro group; R4 is a hydroxyl group or the group -NHZ (Z is hydrogen atom or a lower alkyl group), or an alkali metal salts thereof are useful as an infection control agent. These derivatives excepting compounds of the formula above wherein n is 0 or 1; any one of R1 to R3 is 5-chloro, 5-methoxy or 5-nitro and the remainder is a hydrogen atom; and R4 is a hydroxyl group; and compounds of the formula wherein n is 0 or 1; two of R1 to R3 are 3,5-dichloro or 3,5-dinitro and the remainder is a hydrogen atom; and R4 is a hydroxy group) are novel, and they were first prepared in this invention. |
