With the development of weapons and ammunition to achieve more powerful and safer functional systems, 2,4-dinitroanisole (DNAN), used as an insensitive melt-cast matrix explosive, has received widespread attention. Various countries have conducted significant research and developed a series of DNAN-based explosive formulations in recent years. However, some inherent limitations of DNAN have enormously restricted its comprehensive application in weapons. In this paper, the progress of DNAN research in recent years is systematically reviewed from the aspects of its essential characteristics, such as physical properties (melting point, shrinkage, irreversible expansion, solubility, and mechanical properties), sensitivity and safety, stability, compatibility, and oxygen balance and energy. The advantages and disadvantages of DNAN are analyzed, and methods to solve these limitations are described. Furthermore, several important directions to be studied in future research are highlighted, including the study of DNAN binary eutectic mixtures mechanisms, control of crystal transformation, and improvements in mechanical properties.
