Applications

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.

Notes

Hygroscopic. Moisture sensitive. Incompatible with acids, acid chlorides, acid anhydrides, strong oxidizing agents and carbon dioxide.
