1-Methylpiperazine is used in the preparation of 2-(4-methyl-1-piperazinylmethyl)acrylophenone. It is involved in the preparation of 1-(4-methoxy-phenyl)-4-methyl-piperazine by reacting with 1-chloro-4-methoxy-benzene. It acts as an intermediate in the synthesis of active pharmaceutical ingredients like ofloxacin, rifampicin, clozapine, sildenafil, trifluoperazine and zopiclone. Further, it is used as a mimic template in the preparation of molecularly imprinted microspheres. In addition to this, it is used in the generation of difunctional strong anion-exchange stationary phase from a 1,4-diazacyclohexane derivative.

N-Methylpiperazine is a piperazine derivative that contains a hydroxy group in the para position. It is used as a reagent in organic synthesis, and can be synthesized from ethylenediamine and formaldehyde or pyrocatechol. N-Methylpiperazine has been shown to inhibit the growth of squamous carcinoma by blocking the production of DNA and RNA. The chemical substance also inhibits the synthesis of protein, which is needed for cell division. N-Methylpiperazine also reacts with hydrogen fluoride to form stable complexes.
