1,5-Diazacyclooctane is an organic compound with the formula (CH₂CH₂CH₂NH)₂. It is a colorless oil. 1,5-Diazacyclooctane is a cyclic diamine.[1]

Synthesis and reactions

It is prepared in low yield by the alkylation of hydrazine with 1,3-dibromopropane.[2]

The N-H centers can be replaced with many other groups. As a bis secondary amine, it condenses with aldehydes to give bicyclic derivatives.[3] When treated with transition metal salts, it serves as a chelating ligand.[1]

gollark: I was able to find, *somehow*, what looks like the source of the FM radio native code/app from about four years ago on github.

gollark: I think it would be somewhere between "install original ROM's FM radio app as a privileged system app" (fine) and "reverse engineer SoC FM tuner and implement own frontend" (not doing that).
