Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 5,8-Bis(5-bromo-2-thienyl)-2,3-bis[3-(octyloxy)phenyl]quinoxaline.
5,8-Bis(5-bromo-2-thienyl)-2,3-bis[3-(octyloxy)phenyl]quinoxaline (CAS 1100761-34-9), molecular formula C44H48Br2N2O2S2 and molecular weight 860.80 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, bromine substitution, 5,8-Bis(5-bromo-2-thienyl)-2,3-bis[3-(octyloxy)phenyl]quinoxaline is typically pale yellow to yellow amorphous powder. Its solid-state physicochemical attributes — including a molecular weight of 860.80 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
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.
