Chemical Structure

(2e)-3-[5-(3-bromophenyl)thiophen-2-yl]prop-2-enoic acid CAS 1087784-22-2 chemical structure

Description

The occurrence of (2e)-3-[5-(3-bromophenyl)thiophen-2-yl]prop-2-enoic 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.

(2e)-3-[5-(3-bromophenyl)thiophen-2-yl]prop-2-enoic acid (CAS 1087784-22-2) is a high-purity analytical reference standard with the molecular formula C13H9BrO2S and a molecular weight of 309.18 g/mol.

Owing to a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution, an aromatic ring system, (2e)-3-[5-(3-bromophenyl)thiophen-2-yl]prop-2-enoic acid is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 309.18 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

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.
