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.
CATO supplies 1,3-Bis(5-bromo-2-thienyl)-5,7-bis(2-butyloctyl)-4H,8H-benzo[1,2-c:4,5-c′]dithiophene-4,8-dione (CAS 2093197-75-0), a certified reference material (molecular formula C42H54Br2O2S4, MW 878.94 g/mol) for analytical method development and quality control.
Owing to a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution, a polycyclic aromatic system, 1,3-Bis(5-bromo-2-thienyl)-5,7-bis(2-butyloctyl)-4H,8H-benzo[1,2-c:4,5-c′]dithiophene-4,8-dione is typically pale yellow to yellow amorphous powder. Its solid-state physicochemical attributes — including a molecular weight of 878.94 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
