3-(4-methoxyphenyl)but-2-enoic acid CAS 19169-94-9

Description

Compared with other compounds in its class, the molecular weight of 192.21 g/mol gives 3-(4-methoxyphenyl)but-2-enoic acid distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies 3-(4-methoxyphenyl)but-2-enoic acid (CAS 19169-94-9), a certified reference material (molecular formula C11H12O3, MW 192.21 g/mol) for analytical method development and quality control.

Based on its molecular formula C11H12O3, 3-(4-methoxyphenyl)but-2-enoic acid contains a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 192.21 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
