Phenylhydrazine e na le monko o ikhethang. Ke sesebelisoa se matla sa ho fokotsa le chelating se ka etsang li-complexes tse tsitsitseng tse nang le li-ion tse ngata tsa tšepe. Lits'ebetsong tsa lik'hemik'hale, phenylhydrazine e ka kopana le aldehydes, ketone le metsoako e meng ho etsa metsoako ea amine e lumellanang.

 

Phenylhydrazine e sebelisoa haholo ha ho etsoa li-dyes, li-fluorescent agents, hape e sebelisoa e le moemeli oa ho fokotsa kapa chelating ho organic synthesis. Ho phaella moo, e ka boela ea sebelisoa ha ho etsoa li-preservatives, joalo-joalo.
