Chemical Structure

4,6-Dibromo-3-fluorothieno[3,4-b]thiophene-2-carboxylic acid CAS 1628427-36-0 chemical structure

Description

The occurrence of 4,6-Dibromo-3-fluorothieno[3,4-b]thiophene-2-carboxylic acid is closely related to a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine/bromine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies 4,6-Dibromo-3-fluorothieno[3,4-b]thiophene-2-carboxylic acid (CAS 1628427-36-0), a certified reference material (molecular formula C7HBr2FO2S2, MW 360.02 g/mol) for analytical method development and quality control.

Structurally, 4,6-Dibromo-3-fluorothieno[3,4-b]thiophene-2-carboxylic acid (C7HBr2FO2S2) contains a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine/bromine substitution, an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 6.0, corresponding to approximately 6 ring(s) or double-bond equivalent(s). With a molecular weight of 360.02 g/mol, it falls into the moderately-high-molecular-weight range. 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.
