Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 406.18 g/mol gives 3,3''-Dibromo-2,2':5',2''-terthiophene distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
3,3''-Dibromo-2,2':5',2''-terthiophene (CAS 790712-86-6) is a high-purity analytical reference standard with the molecular formula C12H6Br2S3 and a molecular weight of 406.18 g/mol.
Structurally, 3,3''-Dibromo-2,2':5',2''-terthiophene (C12H6Br2S3) contains sulfur-containing functionality, bromine substitution, an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 9.0, corresponding to approximately 9 ring(s) or double-bond equivalent(s). With a molecular weight of 406.18 g/mol, it falls into the moderately-high-molecular-weight range. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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.
