Bis(1,2,4‐oxadiazolyl) Furoxan: A Promising Melt‐Castable Eutectic Material of Low Sensitivity

A scalable synthesis of bis(1,2,4‐oxadiazoyl) furoxan, C6H2N6O4, its physical properties, and its theoretical performance values are described. Previous attempts to synthesize this compound required expensive reagents, and/or time‐consuming synthesis processes and low overall yields. In addition to disclosing a streamlined synthesis of bis(1,2,4‐oxadiazolyl) furoxan, we report its molecular configuration and crystal structure, as well as its correct melting point. Bis(1,2,4‐oxadiazolyl) furoxan exhibits a very insensitive behavior to impact, friction, and electrostatic discharge, with a calculated detonation pressure 20 % higher than that of TNT. Given its physical properties and theoretical performance values, this material can be classified as a promising ingredient in the development of melt‐castable eutectic technology.
