Chemical Structure

methyl 4-(piperazin-1-yl)butanoate CAS 1096345-74-2 chemical structure

Description

methyl 4-(piperazin-1-yl)butanoate (CAS 1096345-74-2) is a high-purity analytical reference standard with the molecular formula C9H18N2O2 and a molecular weight of 186.25 g/mol.

Based on its molecular formula C9H18N2O2, methyl 4-(piperazin-1-yl)butanoate contains an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage; these features give the compound characteristic functional-group stretching vibrations in infrared spectroscopy. The molecular weight of 186.25 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
