A fluorinated o-phenylenediamine building block

For the synthesis of Schiff bases in applications of APIs and batteries


4-Fluoro-1,2-phenylenediamine (CAS number 367-31-7) is a fluorinated ortho-phenylenediamine. 4-Fluoro-1,2-phenylenediamine serves as a hardener for epoxy resins to enhance their thermal conductivity, thereby improving the thermal management of electrical motors and integrated circuits. The ortho-positioning of the amine groups enables 4-fluoro-1,2-phenylenediamine to form salen-type Schiff bases with salicylaldehydes. Such Schiff bases can coordinate to Co, Ni, Cu and Zn, affording corresponding organometallic complexes. The salen-type Schiff bases metal complexes show multiple applications, such as antimicrobial agents and redox carriers for flow batteries.

4-Fluoro-1,2-phenylenediamine is also utilized in the synthesis of 2,3-diaminophenazines through an oxidative reaction. 2,3-diaminophenazines have a wide range of applications in dyes and drug discovery.
