2,5-Bis(5-bromo-3-tetradecylthiophen-2-yl)thieno[3,2-b]thiophene CAS 1246521-88-9

Description

Compared with other compounds in its class, the molecular weight of 855.01 g/mol gives 2,5-Bis(5-bromo-3-tetradecylthiophen-2-yl)thieno[3,2-b]thiophene distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

2,5-Bis(5-bromo-3-tetradecylthiophen-2-yl)thieno[3,2-b]thiophene (CAS 1246521-88-9), molecular formula C42H62Br2S4 and molecular weight 855.01 g/mol, is a CATO reference standard with documented purity and traceability.

2,5-Bis(5-bromo-3-tetradecylthiophen-2-yl)thieno[3,2-b]thiophene (C42H62Br2S4) 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 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.
