2,6-Dibromo-4,4-dihexyl-4H-silolo[3,2-b:4,5-b']dithiophene CAS 188690-66-6

Description

The occurrence of 2,6-Dibromo-4,4-dihexyl-4H-silolo[3,2-b:4,5-b']dithiophene is closely related to sulfur-containing functionality, bromine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

2,6-Dibromo-4,4-dihexyl-4H-silolo[3,2-b:4,5-b']dithiophene (CAS 188690-66-6), molecular formula C20H28Br2S2Si and molecular weight 520.46 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to sulfur-containing functionality, bromine substitution, an aromatic ring system, 2,6-Dibromo-4,4-dihexyl-4H-silolo[3,2-b:4,5-b']dithiophene is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 520.46 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.

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.
