1-Methylpiperazine Usage And Synthesis

Chemical Properties

clear liquid

Uses

1-Methylpiperazine is used in the preparation of 2-(4-Methyl-1-piperazinylmethyl)acrylophenone(MPMAP)

Uses

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.

Definition

ChEBI: 1-Methylpiperazine is a N-methylpiperazine.

Hazard

Moderate fire risk.

Flammability and Explosibility

Flammable

Safety Profile

Poison by intraperitoneal route. Moderately toxic by inhalation, ingestion, and skin contact. A severe skin and eye irritant. Flammable liquid when exposed to heat or flame; can react with oxidizing materials. To fight fire, use alcohol foam, CO2, dry chemical. When heated to decomposition it emits toxic fumes of NOx.
