Uses: 

Centralite ll is a gunshot residue also known as ethyl centralite. It is mainly used as a burning rate moderator and stabilizer for smokeless powder, and also a plasticizer for celluloid.

Smokeless powder deterrents:

All hydrocarbon-substituted symmetrical diphenyl urea compounds used as smokeless powder deterrents (or moderants) were called centralites after the laboratory. The preferred ethyl centralite became known as CentraliteⅠ and the original methyl centralite was identified as Centralite ll. Butyl centralite was also used as a celluloid plasticizer.
