Chemical Structure

1-(But-3-ynyl)-4-(pyridin-2-yl)piperazine CAS 142891-45-0 chemical structure

Description

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.

1-(But-3-ynyl)-4-(pyridin-2-yl)piperazine (CAS 142891-45-0), molecular formula C13H17N3 and molecular weight 215.29 g/mol, is a CATO reference standard with documented purity and traceability.

Based on its molecular formula C13H17N3, 1-(But-3-ynyl)-4-(pyridin-2-yl)piperazine contains a nitrogen-containing heterocyclic scaffold, a nitrile group; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 215.29 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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.
