DIPHENYL Chemical compatibility with O-rings, rubbers, & plastics

Diphenyl, also known as biphenyl, is a colorless crystalline compound with the chemical formula C12H10. It is used as a heat transfer fluid, in the manufacture of certain chemicals, and as a fungistat for citrus fruits. Diphenyl is relatively non-toxic but can cause skin and respiratory irritation upon exposure. Proper handling, storage, and the use of personal protective equipment (PPE) are essential to ensure safety when working with this chemical.
