4-Bromo-2-(3-methoxyphenyl)thiophene CAS 1078734-22-1

Description

The occurrence of 4-Bromo-2-(3-methoxyphenyl)thiophene is closely related to sulfur-containing functionality, 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.

4-Bromo-2-(3-methoxyphenyl)thiophene (CAS 1078734-22-1) is a high-purity analytical reference standard with the molecular formula C11H9BrOS and a molecular weight of 269.16 g/mol.

4-Bromo-2-(3-methoxyphenyl)thiophene (C11H9BrOS) contains sulfur-containing functionality, a hydroxyl group, an ether linkage, bromine substitution, an aromatic ring system. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
