Provided is a compound that thickens and/or gelatinizes a fluid organic substance to a desired viscosity, or uniformly stabilizes a composition containing the fluid organic substance. Also provided are: a thickening/stabilizing agent including the compound, a thickened/stabilized composition including the thickening/stabilizing agent and a fluid organic substance, and a method for producing the composition. The compound according to the present invention is represented by Formula (1): €ƒ€ƒ€ƒ€ƒ€ƒ€ƒ€ƒ€ƒ(R 2 -HNOC) 4-n -R 1 -(CONH-R 3 ) n €ƒ€ƒ€ƒ€ƒ€ƒ(1) where R 1 is a group resulting from removing four hydrogen atoms from the structural formula of an aromatic hydrocarbon or cyclohexane； R 2 is, independently in each occurrence, an aliphatic hydrocarbon group containing 1 to 4 carbon atoms； R 3 is, independently in each occurrence, an aliphatic hydrocarbon group containing 6 or more carbon atoms； and n is an integer of 1 to 3.
