2,6-Dibromo-4,4-bis(6-bromohexyl)-4H-cyclopenta[2,1-b:3,4-b']dithiophene CAS 1426829-76-6 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 662.18 g/mol gives 2,6-Dibromo-4,4-bis(6-bromohexyl)-4H-cyclopenta[2,1-b:3,4-b']dithiophene distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies 2,6-Dibromo-4,4-bis(6-bromohexyl)-4H-cyclopenta[2,1-b:3,4-b']dithiophene (CAS 1426829-76-6), a certified reference material (molecular formula C21H26Br4S2, MW 662.18 g/mol) for analytical method development and quality control.

2,6-Dibromo-4,4-bis(6-bromohexyl)-4H-cyclopenta[2,1-b:3,4-b']dithiophene (C21H26Br4S2) contains sulfur-containing functionality, bromine substitution, a polycyclic aromatic 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 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.
