Description

Compared with other compounds in its class, the molecular weight of 205.28 g/mol gives 3-(5-Methylthiophen-2-yl)-N-(prop-2-yn-1-yl)acrylamide distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies 3-(5-Methylthiophen-2-yl)-N-(prop-2-yn-1-yl)acrylamide (CAS 1258829-18-3), a certified reference material (molecular formula C11H11NOS, MW 205.28 g/mol) for analytical method development and quality control.

Structurally, 3-(5-Methylthiophen-2-yl)-N-(prop-2-yn-1-yl)acrylamide (C11H11NOS) contains a nitrogen-containing heterocyclic scaffold, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 7.0, corresponding to approximately 7 ring(s) or double-bond equivalent(s). With a molecular weight of 205.28 g/mol, it falls into the medium-molecular-weight range. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.
