2-(4-Bromothiophen-3-yl)acetic acid CAS 1504282-77-2

Description

The occurrence of 2-(4-Bromothiophen-3-yl)acetic acid is closely related to a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

2-(4-Bromothiophen-3-yl)acetic acid (CAS 1504282-77-2) is a high-purity analytical reference standard with the molecular formula C6H5BrO2S and a molecular weight of 221.07 g/mol.

The molecular framework of 2-(4-Bromothiophen-3-yl)acetic acid (C6H5BrO2S) is characterized by a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution, an aromatic ring system. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.
