Chemical Structure

2-(4-Bromothiophen-3-yl)-2-methylpropanoic acid CAS 1528989-30-1 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 249.12 g/mol gives 2-(4-Bromothiophen-3-yl)-2-methylpropanoic acid distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies 2-(4-Bromothiophen-3-yl)-2-methylpropanoic acid (CAS 1528989-30-1), a certified reference material (molecular formula C8H9BrO2S, MW 249.12 g/mol) for analytical method development and quality control.

2-(4-Bromothiophen-3-yl)-2-methylpropanoic acid (C8H9BrO2S) contains a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution, an aromatic ring system. Halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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.
