n-(But-3-yn-1-yl)-n-methylaniline CAS 137273-33-7 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 159.23 g/mol gives n-(But-3-yn-1-yl)-n-methylaniline distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies n-(But-3-yn-1-yl)-n-methylaniline (CAS 137273-33-7), a certified reference material (molecular formula C11H13N, MW 159.23 g/mol) for analytical method development and quality control.

Structurally, n-(But-3-yn-1-yl)-n-methylaniline (C11H13N) contains a nitrogen-containing heterocyclic scaffold, a nitrile group. The molecule exhibits a degree of unsaturation (DBE) of 6.0, corresponding to approximately 6 ring(s) or double-bond equivalent(s). With a molecular weight of 159.23 g/mol, it falls into the medium-molecular-weight range. 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.
