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

A highly selective molecularly imprinted solid-phase extraction (MISPE) combined with liquid chromatography-ultraviolet detection was developed for the simultaneous isolation and determination of four plant hormones including indole-3-acetic acid (IAA), indole-3-propionic acid (IPA), indole-3-butyric acid (IBA) and 1-naphthaleneacetic acid (NAA) in

Liquid chromatography-tandem mass spectrometry is one of the most sensitive tools for determination of trace amounts of analytes in metabolomics and proteomics. The highest sensitivity is achieved in selected reaction monitoring detection, which involves fragmentation of the molecular ion between
