Chemical Structure
Description
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 2,6-Dibromo-4-n-octyldithieno-3,2-b:2',3'-d]pyrrole (CAS 1346688-54-7), a certified reference material (molecular formula C16H19Br2NS2, MW 449.27 g/mol) for analytical method development and quality control.
Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality, bromine substitution, 2,6-Dibromo-4-n-octyldithieno-3,2-b:2',3'-d]pyrrole is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 449.27 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
