Chemical Structure
Description
CATO supplies 2,6-Dibromo-4,4-didodecyl-4H-cyclopenta[2,1-b:3,4-b']dithiophene (CAS 1235873-96-7), a certified reference material (molecular formula C33H52Br2S2, MW 672.70 g/mol) for analytical method development and quality control.
2,6-Dibromo-4,4-didodecyl-4H-cyclopenta[2,1-b:3,4-b']dithiophene (C33H52Br2S2) 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.
