The invention discloses a method for analysis of FOX-7 content. The method comprises the following steps of dissolving FOX-7 in dimethylformamide as a solvent, titrating the FOX-7 solution to an equipotential point on a potentiometric titrator by a tetrabutylammonium hydroxide standard solution prepared by methyl alcohol, carrying out blank titration, determining a chemical reaction endpoint by a potentiometric titration curve according to an electrode potential jump, and calculating FOX-7 content according to the formula shown as below: omega=((V1-V01)/1000*c*148.08g*mol<-1>)/m1*100%, wherein omega represents FOX-7 content (%); V1 represents the volume (ml) of the tetrabutylammonium hydroxide standard solution consumed by a sample; V01 represents the volume (ml) of the tetrabutylammonium hydroxide standard solution consumed by a blank sample; c represents a concentration (mol*l<-1>) of the tetrabutylammonium hydroxide standard solution; FOX-7 molar mass is 148.08 g*mol<-1>; and m1 represents FOX-7 mass (g). The method provided by the invention realizes determination of FOX-7 content creatively by a non-aqueous titration method and has a small use amount of a sample. The method provided by the invention has the advantages of simple operation, high precision, accurate content and good repeatability.
