General description

1-Methylpiperazine is a heterocyclic diamine used as a versatile building block and intermediate in organic synthesis.

Application

1-Methylpiperazine was used as mimic template in the preparation of molecularly imprinted microspheres (MIMs). It was also used to prepare the difunctional strong anion-exchange stationary phase from a 1,4-diazacyclohexane derivative.

This paper reports the preparation of a novel, silica-based, strong anion-exchange stationary phase from a 1,4-diazacyclohexane derivative. To prepare the difunctional strong anion-exchange stationary phase, activated silica beads were first bonded with 3-chloropropyltriethoxysilane and then reacted with 1-methylpiperazine followed by
